I took a few moments to carefully align the charging coil in my phone with the holder and it works a lot better than some reviews suggest. Even with the Samsung case on, it charges from a few mm apart. With Waze going, it seems to hold the battery at a steady % rather than charge the phone, but it's not discharging so that's OK. Phone gets quite warm though.
At full reach, in my car with firm suspension, carrying a Samsung 9+, it does wobble a little bit, not too much to be a problem, but could do with being thicker and more solid. As is a pals £1 holder from £1 store or somewhere, alas that's not wireless charging, but is very sturdy and has more reach.
And for my car and my usage, it needs another few inches reach, seems that the v5 might have some extra.
The articulation is good and allows fairly good positioning, but a sufficiently stiff 'gooseneck arm', if there was one, and in different lengths, would do better.
The arms seem to grip the phone well & click on fast & firmly.
The charging wire is far to short, and it would be nice if the charging wire was integrated somehow. It's a nice extra that the plug has a USB outlet on it's top.
Service from Mobile Fun was very good.
