Rokform Magnetic Sport Ring Grip V2 Review: The Best Grip for Rokform Cases?

If you’ve ever had your phone slip out of your hand stepping off a bike, or you’re forever propping it against a coffee mug just to watch a video, a good ring grip fixes both problems at once. The Rokform Magnetic Sport Ring Grip V2 is Rokform’s take on that accessory, and it does the job with a twist most rivals skip.

The Sport Ring Grip V2 (model 337301-V2) is a metal ring grip and two-way kickstand that clicks onto the back of your phone with Rokform’s RokLock twist-lock system instead of adhesive. It’s built from stainless steel, aluminum, titanium, and fiber-reinforced polymer, carries a 2-year warranty, and sells for about $40. On Amazon it holds a 4.5-star average across roughly 125 ratings.

There’s one thing you have to know before anything else, and it’s the whole story of this product: it only works with Rokform RokLock cases. This is not a stick-on ring you can slap on any phone. If you’re already in the Rokform ecosystem, that catch turns into a feature. If you’re not, it changes the math completely.

I spent time with the V2 on an iPhone 17 Pro Max in a Rokform rugged case to find out whether the metal build and the twist-lock design earn their price, and where the ring grip falls short.

What I Liked

After living with the Sport Ring Grip V2 on a daily-carry phone, six things kept standing out.

All-Metal Build That Feels Built to Last

Pull the ring out of the box and the first thing you notice is the weight. This is stainless steel, aluminum, titanium, and fiber-reinforced polymer, not the hollow plastic you get on a stick-on ring. It has the same rugged, machined look as the rest of Rokform’s lineup.

That heft translates into confidence. The hinge moves smoothly but holds its position, the finish shrugs off scuffs, and nothing about it feels like a throwaway accessory. Rokform pitches this as the last ring grip you’ll buy for the phone, and the hardware backs that up.

Twist-Lock On and Off in Seconds, No Adhesive

Instead of glue, the V2 uses Rokform’s RokLock system. You line up four prongs with the mount on the back of a Rokform case, push, and give it a quarter twist until you hear the click that means it’s locked. Taking it off is the same move in reverse, and the whole thing takes about two seconds.

This is the feature that sets it apart. Most ring grips are glued on for good, so they block wireless charging and get in the way of a car mount forever. With the RokLock ring, you twist it off when you need a clear back and twist it on when you want the grip.

A Sturdy Two-Way Kickstand

Flip the ring open and it doubles as a stand that works in both portrait and landscape. The swivel has enough rigidity to prop the phone at a range of angles without sagging, and one gym-goer on Amazon noted it’s “stiff enough to double as a kickstand” while still being loose enough to hang the phone off a hook.

For watching a video on a desk or following a recipe on the counter, it does the job without a separate stand.

A Grip That’s Built for Active Use

The “sport” in the name is earned. A ring like this genuinely changes how secure a big phone feels in a small hand, whether you’re texting while carrying groceries or holding the phone one-handed on the move. One buyer who lives with Parkinson’s said the Rokform system “makes it incredibly easy to hold onto” and cut down the drops that used to wreck their phones.

Cyclists, motorcycle riders, and gym-goers already in the Rokform ecosystem get the most out of it, since the ring pairs with the mounts they already own. The same ecosystem logic extends to charging at the desk, where the Rokform Magnetic Wireless Charger with Stand props the phone upright with a magnet strong enough to grip through a rugged case. For that same active user living out of a gym bag, a single TOP-UP 4-in-1 Magnetic Charging Cable keeps a phone, watch, and earbuds charging from one cord on the road.

A Magnet That Sticks to Metal Surfaces

Built into the ring is a magnet strong enough to stick the phone to metal. Gym users park their phone on the rack to track a workout, and one reviewer even mounts theirs to a forklift roll cage. On r/MagSafe, a Rokform owner summed up the pull: “It takes two hands to take my phone off the fridge.”

It’s a bonus rather than the main event, and I’ll get to its limits below, but for grabbing a hands-free spot on any metal surface it’s handy. For a magnet tuned to MagSafe chargers and car mounts rather than bare metal, an iPhone case like the Spigen Tough Armor T iPhone 17 Pro Max builds that stronger ring right in. The TORRAS Magnetic iPhone 17 Pro Max case does the same with 38 N56-grade magnets that grip accessories firmly while still passing wireless charging through.

One Ring You Can Reuse Across the Ecosystem

Because it clicks into the same RokLock mount as Rokform’s car vents, bike mounts, and wall docks, the ring is part of a system rather than a dead-end purchase. It also ships with a 2-year limited warranty, which is longer than most grips bother to offer.

If you’re already buying into Rokform gear, that swap-anywhere flexibility is a real reason to add the ring to the cart.

What Needs Improvement

The Sport Ring Grip V2 is a good piece of hardware held back by a few real limits. Four are worth knowing before you spend the money.

It Only Works With Rokform RokLock Cases

This is the big one. The V2 is not a stick-on ring — it clicks into the RokLock twist mount, so it only works on a Rokform case for iPhone, Samsung, or Pixel. If you don’t already own one, the ring is really only half the purchase; you’re signing up for a case too.

Rokform sells a Universal Adapter that adds the mount to a non-RokLock case, but that’s an extra step and an extra part. Out of the box, plan on being in the Rokform ecosystem or the ring simply won’t attach.

No Wireless Charging While It’s Attached

The onboard magnet is weaker than the strong magnet in Rokform’s rugged cases, and with the ring locked on you can’t wirelessly charge at all. One Amazon owner put it plainly: the ring “works well but can’t be used with the wireless charger.”

The workaround is built into the design — twist the ring off, charge, twist it back on — but it’s a genuine daily friction if you’re used to just setting the phone on a pad. If wireless charging with a grip attached is a must, this isn’t the ring for you.

It Adds Real Bulk and Weight

Solid metal has a downside. Attached to the phone, the ring adds noticeable thickness and weight, and it can make the phone less comfortable to slide into a pocket. One reviewer who liked the build still called it “a bit too bulky for everyday use.”

It’s the trade-off for the rugged feel, and active users won’t mind, but anyone chasing a slim profile should go in expecting it.

A Slight Wiggle and Occasional Stand Sag

When the ring is seated, it has a slightly looser fit and can rattle a little. Rokform says this is intentional to reduce strain on the hinge, and it’s still secure, but it surprises people at first. The V2’s no-slip section also dropped the textured finish the older 337301 model had, though it still keeps the phone from sliding.

A few owners note the stand can collapse under the weight of a large phone and case in certain angles. It holds fine in most positions, but it isn’t rock-solid in every one.

How It Compares

Most phone grips today are universal MagSafe accessories that stick to any phone. The Rokform plays a different game, so the comparison is really about whether you want a locked-in system or a go-anywhere magnet.

vs. PopSockets MagSafe and Spigen Nano Pop

The PopSockets MagSafe grip and Spigen’s Nano Pop are the mainstream picks, running roughly $17 to $30 and snapping onto any MagSafe phone or case. They’re cheaper, lighter, and don’t lock you into one brand. What they don’t give you is a hard mechanical mount — they’re magnet-only, so they pull off more easily and lean plastic where the Rokform is metal. Choose the universal grips if you want cheap and flexible; choose the Rokform if you want a ring that clicks in and won’t shift.

vs. Benks ArmorPop and OhSnap Snap Grip

WIRED named the Benks ArmorPop its best kickstand-and-grip combo, an aramid-fiber grip with a finger strap and a metal stand for about $27, while the OhSnap Snap Grip uses adhesive plus magnets to stay put and keep working with other MagSafe mounts. Both keep MagSafe passthrough that the Rokform blocks. The Rokform counters with a sturdier all-metal build and the twist-lock security that suits hard, active use. If you want to keep wireless charging, the Benks or OhSnap wins; if you want the most secure hold, the Rokform does.

Where the Rokform Wins

The Sport Ring Grip V2 makes sense only inside its own ecosystem, but there it has no real rival. No universal grip clicks into a car vent, bike mount, and wall dock with one twist, and few match the metal construction. For a Rokform owner, the ring completes a system rather than adding another loose accessory.

Final Verdict

The Rokform Magnetic Sport Ring Grip V2 is a well-built metal grip and two-way kickstand that shines for one specific person: the owner of a Rokform RokLock case.

I’m giving it a 4.3 out of 5.

It loses a few tenths for the things that box it in — it only works with Rokform cases, it blocks wireless charging while attached, it adds real bulk, and the seated ring has a slight wiggle. None of that is a dealbreaker for its intended user. The metal build, the twist-on-and-off convenience, the sturdy stand, and the 2-year warranty earn the rating back.

Bottom line: if you’re already in the Rokform ecosystem and want the most secure, reusable grip you can bolt onto that case, this is an easy add. If you’re not a Rokform owner, a universal MagSafe grip will serve you better for less.
