It's exactly what it advertises and does everything I need it to. Enough space to fit my phone, readers, car keys, AirPods, wallet, and a little extra space for a small candle. I only wish the slot for the charging cable was a bit smaller sometimes the charging cable will slide out since there is nothing to catch it or secure it in place.

Not functional

Tree part is very cheaply made plastic material and does not fit well into the stand at all

Don’t bother, not worth the $

Much smaller in person than it appears. Looks more like a piece of coral than a tree. I got this to display some ornaments for sale at craft fairs, but it’s so small, it looks silly with the ornaments on it. Super flimsy, made of cheap plastic. Definitely not worth $14. Will be returning.
