Wobbles a bit.

Mobile even fits even with the big battery, good in the cradle. I think that has as yet no written and before I ordered this kit I have namely the same thing asked. Fits the phone even if the larger good pure battery (I mean the original Samsung) is installed. And yes, it does, and without problems.
Easy to assemble, makes a pretty high-quality impression. However, the holder wobbles on the grating a bit.
