Very good but won't work with a case
This works just as I thought it would with my LG G5 phone and also works with my Google Pixel.  In fact, it works even better with the Pixel because you can leave the case on the Pixel.  The Pixel is slightly narrower than the G5 so with a thin case it still fits in the slot however because of the tight tolerances the extra width added by even a thin case is too much for the G5 to fit .  Luckily,  my case is very easy to remove and so at night I just pop the phone out of the case and into the stand where the phone doubles as a bedside clock.  It also works great to charge a spare G5 battery.
