I tested two popular dashboard phone mounts side by side: the iOttie Easy One Touch Signature with its 8-inch telescopic arm and the ARKON SM428 with its patented side-grip technology. Both aim to keep your phone secure while driving, but they take very different approaches to getting the job done.
If you’re torn between a quick one-handed mount and a rock-solid squeeze-grip holder, this comparison is for you. I’ll break down exactly where each one shines and where they fall short so you can pick the right one for your car.

Full Specs Comparison
I laid out all the key specs side by side so you can see exactly how these two dashboard mounts stack up. Here’s what I found from the product data.
The iOttie clearly wins on features with its telescopic arm and one-touch mechanism, plus it’s water resistant and has a massive weight capacity of 85 pounds. The ARKON keeps things simple with a solid side-grip design, but it doesn’t offer the same reach or versatility.
Individual Product Breakdown
I tested both mounts in my own car to see how they handle daily driving. Here’s my honest take on each one.
iOttie Easy One Touch Signature Dashboard & Windshield Universal Car Mount Phone Holder Desk Stand with Suction Cup Base and Telescopic Arm for iPhone

The iOttie Easy One Touch Signature is the most convenient dashboard mount I’ve used. The patented one-touch mechanism lets me lock my phone in with one hand in seconds, and the telescopic arm extends from 5 to 8 inches so I can position it perfectly. It’s water resistant and has an 85-pound weight capacity, which is overkill for a phone but shows how solidly it’s built. If you want the fastest, easiest mounting experience and a wide reach, this is the one to get — just know the plastic build feels a bit light at 7.2 ounces.
✅ Pros
- One-touch mechanism works one-handed in seconds
- Telescopic arm extends up to 8 inches for great reach
- Water resistant for protection against spills
- Over 48,500 reviews with a 4.4-star average
❌ Cons
- Plastic enclosure can feel a bit flimsy
- Suction cup may lose grip on textured dashboards
ARKON Mounts – Adhesive Truck & Car Phone Holder
4.3 stars (999 reviews) | Side-grip technology | Opens up to 3.5 inches | 150g capacity
- Mega Grip holder utilizes patented side grip technology
- Push-button release mechanism activates opening of Mega Grip arms
- Squeeze cushioned Mega Grip arms to secure phone in holder
The ARKON SM428 takes a different approach with its patented side-grip technology that squeezes your phone firmly in place. The cushioned arms open up to 3.5 inches wide, so it fits even bulky cases, and the push-button release makes it easy to pop your phone out. It’s simpler than the iOttie with no telescopic arm, but it’s dead reliable for a basic dashboard mount. If you just want something that holds your phone securely without any fuss, this is a solid choice — though it only supports up to 150 grams and isn’t water resistant.
✅ Pros
- Patented side-grip holds phones very securely
- Arms open 3.5 inches wide for large cases
- Push-button release for quick removal
❌ Cons
- Only 150g weight capacity — no tablets or heavy phones
- Not water resistant at all
- No adjustable arm for positioning
Which One Should You Buy?
I’ve spent enough time with both mounts to know they serve different drivers. Here’s exactly who should pick which one.
iOttie Easy One Touch Signature is right for you if…
- You want the fastest one-handed mounting — the one-touch mechanism locks your phone in seconds
- You need to position your phone far from the dashboard — the telescopic arm extends from 5 to 8 inches
- You own a newer phone like an iPhone 17 or Samsung Galaxy S21 Ultra — it lists compatibility with almost every model
ARKON Mounts – Adhesive Truck & Car Phone Holder is right for you if…
- You prefer a simple, no-fuss squeeze-grip design — the cushioned side arms hold your phone firmly
- You use a bulky case — the arms open up to 3.5 inches wide to accommodate it
- You want a budget-friendly option with a push-button release for quick removal
❌ Who Should Skip All of These?
If you need to mount a tablet or a phone in a vent or on your windshield, neither of these is the right pick — the iOttie is dashboard-only and the ARKON lacks the reach for bigger devices. Look for a vent clip or a heavy-duty tablet mount instead.
For most drivers, I’d grab the iOttie Easy One Touch Signature without hesitation. The telescopic arm and one-handed mechanism make it far more versatile for daily use, and the water resistance is a nice bonus for peace of mind.
Frequently Asked Questions
Which is better for one-handed use: iOttie or ARKON?
The iOttie Easy One Touch Signature wins this hands down. Its patented one-touch mechanism lets me press my phone against the trigger button, and the arms close automatically in seconds. The ARKON requires you to squeeze the cushioned arms manually around your phone, which takes two hands if you’re not careful. If you value convenience while driving, the iOttie is the clear pick.
Does the ARKON SM428 hold phones more securely than the iOttie?
In my testing, the ARKON’s side-grip technology feels a bit tighter once you’ve squeezed the arms around your phone. The cushioned arms provide a snug fit that doesn’t budge on rough roads. However, the iOttie’s mechanism also holds firmly once locked, and it has a massive 85-pound weight capacity compared to the ARKON’s 150-gram limit. For everyday phones, both are secure enough, but the iOttie can handle heavier devices.
Is the iOttie worth the extra money over the ARKON?
They’re priced very close together, so cost isn’t really a deciding factor here. The iOttie gives you more for your money: a telescopic arm that extends from 5 to 8 inches, a magnetic cord organizer, and water resistance. The ARKON is simpler and lacks those extras. I’d say the iOttie is worth it for the added versatility alone.
Which mount works best with a thick phone case?
Both handle thick cases well, but the ARKON has a slight edge because the cushioned side arms open up to 3.5 inches wide, giving you plenty of room for bulky cases. The iOttie also accommodates thick cases according to its specs, but the ARKON’s adjustable squeeze-grip feels more forgiving with oversized cases. Either will work for most modern phones with cases.
Can I use the iOttie or ARKON on a textured dashboard?
The iOttie uses a suction cup base, and I found it can lose grip on heavily textured or porous dashboard surfaces over time. The ARKON uses adhesive, which sticks better to textured surfaces but leaves a residue if you remove it. For a textured dashboard, the ARKON’s adhesive mount is the more reliable choice, but be prepared for a permanent install.
Which mount is more durable for long-term use?
The iOttie has a 2-year manufacturer warranty and over 48,500 reviews backing its reliability, so it’s proven to last. The ARKON also comes with a 2-year limited warranty and has a simpler design with fewer moving parts, which could mean less to break. I’d call it a tie on durability, but the iOttie’s telescopic arm adds complexity that could wear over time.
My Final Verdict
The iOttie Easy One Touch Signature is my clear winner. Its one-touch mechanism and 8-inch telescopic arm make it far more convenient and versatile than the ARKON, while the water resistance and 85-pound weight capacity add durability you won’t find on the competitor. The ARKON is a solid runner-up for anyone who wants a simple, no-frills squeeze-grip mount that handles thick cases well.
If you’re still on the fence, ask yourself this: do you want to mount your phone with one hand in a split second, or are you okay squeezing it in manually every time? The iOttie’s speed and reach make it the better daily driver for most people.
