CHOETECH makes many charging options with both standard and fast wireless charging pads. And the T811C is a nice low cost standard QI wireless charger.
The rubber grips do hold the phone in place better than many other units. Having a phone held in place is a personal preference with some preferring a phone to slide easily into their hands, and others preferring a phone to be held better.
The CHOETECH T811C is a good low cost unit that does what it is meant to do which is charge a QI capable phone wirelessly.
For example the Galaxy S6 has wireless charging but not fast charging so a standard QI charger would likely be best.
Fast Charging phones such as the Galaxy S6 Edge, S7 and so on would benefit from a fast charging pad.
Most all wireless QI charging units are compatible with a QI enable phone so it really comes down to how fast you need your phone charged.
Of course using a cable is still much faster than wireless charging but is a nice option to have around.
As always be sure to read the reviews on Amazon or elsewhere to be sure a unit is a good fit for you.
