Good phone holder…

Good entry-level phone holder. Does the job on a road bike.

Good but..

Excellent easy product, stable but very narrow for a cell phone with a slim cover, unusable with a more protective cover, difficulty extracting the cell phone. If used with maps it becomes a toaster oven. So good but not great, because using the mobile phone without a cover (very thin Oppo A94) the risk of it falling when you take it out or use it is not the greatest.

Can be better. Fit is too tight for 6.7" screen.

It does what it says

The ideal low-cost solution. The packaging holds up well, tested even in the forest. The display on the phone is easy to read, the phone is easy to use. So it is definitely more suitable for a longer stem, I have 80 mm and there is enough for a tight fit. But he climbed in, so satisfaction.

Support used under a…

Support used in heavy rain and my phone was well protected. On the other hand, it is a little difficult to program the route… through the plastic.

Great case

It holds well on the handlebars and protects the phone from rain and dust. If you have it in a semi-tightened state, it is very difficult to take the phone (iPhone 11) out. In practice, you have to completely release the case from the handlebars before it can be pulled out. So if you plan to take your phone out regularly while driving, I would recommend another case, otherwise this is a good choice.

Very good value for money, touch screen responds well with plastic, attaches and removes quickly, size just for my 6'5 smartphone (the pocket closes well only without the shell)
