Very solid mount. Not your cheap plastic junk that will break and leave your expensive phone broken on the road. I have a Samsung A20 with Otterbox Defender case and fits. I would recommend this mount to anyone.

Awesome product! This phone mount is incredible! Locks up tight and 100% confidence that my iPhone 11 Max Pro is secure are any speed and any road conditions!

I am using this mount with a 2020 Trek Dual Sport 2. No insert needed just the protective tape. This is a VERY high quality phone mount! Stays solidly in place and holds my S20 Ultra very securely, which is key.

I've only had it for about three weeks, but so far it delivered on everything I read about it before buying. Installed super easy in about 5 minutes and hasn't moved a fraction of an inch since install. Generally my phone is only in it when I'm going somewhere unfamiliar and need to use the GPS. Of course in the back of my mind I worry that it's going to fail and send my phone flying but that's really an unwarranted worry since when I have my phone in the mount, I have yet to see it move even a little. So far this product has delivered and is a 5/5 for me and I'll be recommending to all of my buddies who need a mount.

I’m very satisfied with your product. I wasn’t sure what I was going to get but was pleasantly surprised at the quality and construction of it. I have photos of the mount on my bike. I will highly recommend your product to all my riding buddies

I highly recommend the tackform mount! I have a 2012 Harley electra glide ultra limited and the brake/clutch perch mount works perfectly. It holds my Samsung s10e with a gel type case on it really snug but it's easy to take in and out with one hand. I can see the phone while riding, it doesn't bounce around, it's a solid mount. I don't text or anything while riding of course but I have my phone blutoothed to my radio so I can listen to xm. Customer service is great, I had an issue that was in no way their fault, it was all on me, and tackform went above and beyond my expectations. Great product with great service! It's well worth the money!

I really love this phone holder. It looks good and works great. You can take the phone in and out of the holder with just one hand. Very convenient! I use it on my electric bicycle. Highly recommended!

I’ve always been leery about my phone or GPS unit dying off my bike if I can’t manage to dodge a rough road, a washboard country gravel lane, an unseen speed bump, a lower-than-grade manhole cover or a pothole. I no longer have that concern; my Tackform is perfect. After riding with it on one bike, I immediately ordered a second for my other machine. Love ‘em! Thank you!

this lil sucker holds my $1200 cell phone perfectly. Through rough single track conditions. Great product
