Product Customer Reviews

I was actually looking for a way to mount my phone on my top tube. Between my bike computer and headlight, there really isn't much room on my handlebars/stem for my phone. I don't like my phone bouncing around in my back pocket. I tried a top tube bag but found it too big and my knees would brush against it while riding. It took quite a bit of searching to come across this product. The case can be attached to my top tube and is very secure. There is an additional safety strap to make sure that the velcro does not accidentally become undone. That's a nice little detail. My Samsung Galaxy S8 fits perfectly in this case. It's narrow enough that my legs don't hit it even when I'm out of the saddle. The plastic is touch sensitive, so you can use your phone while in the case. However, you can't really use the side buttons. It is a little bit difficult to pull your phone out of the case. The trick that works well for me is to slide a stiff piece of cardboard between the plastic cover and your phone screen before pulling the phone out. As noted in the description, the case isn't 100% waterproof. I haven't used this in the rain yet, so I can't comment on how well it keeps the water out. The stitching on the side of the case was starting to unravel when I received the case, so I had to run it through my sewing machine to reinforce the stitches.
Awesome products.
Practical, easy and simple
Serves it purpose, but not the easiest to use. Good quality and the touch screen works. Siri on iPhone doesn't work, but i would have hoped that it should. Some kind of a small slit at the back would have been a better design rather than having the phone sit so flush that the Mic doesn't pick up voice. Quite happy but could have been better.
No need for phone holder, this item is a must for bikers, runners
excellent piece of equipment, fits a large smart phone, and the touchscreen still works through the protective cover.
Great product value for money.

Great idea to attach to headstock of the bike
attatches to the top tube of the frame, or the swan-neck, or handlebars, depending on your preference (i like the top tube). used it in the pouring rain. didn't slip, slide, or let any moisture in. brilliant
Lacks padding the full length on the rear. As a result the top of the case/phone may rub against the stem of the handlebars. Remember, British roads and particularly small roads are not that great so lots of bumps. It's ok for what it is and reasonably priced. Fingerprint does not work through the plastic but ok on touch.
Difficult to get in and out of the holder. Doesn’t stay on the bike frame well. A clunky, poorly designed product
At first I was happy with this as it's easy to attach and fits my phone with no problem, but after a few uses, the velcro is not strong enough and it has fallen off in the middle of the road several times in the last week, one time resulting in a cracked screen.
Fell off second time of using. Velcro not good. Had a refund.
Nice bit of kit but too small by about 15-20mm for my smart phone.
