For the price, I am happy with this purchase. This is one of the lower priced bath trays with a wood like material that I could find on multiple sites. I would have preferred the all wood trays, but didn't want to spend $70ish. Overall this one works very well and I would recommend.
Here is what you should know before deciding...
Wine glass holder- doesn't hold standard size wine glass. Main driver of the 3 stars vs. 4 or 5. I have one smaller wine glass that works perfectly. I have placed it beside a standard size glass in the picture to show the difference. The glass with snowflakes on the right is the one that fits.
Flip-up book metal rod could be sturdier- but it holds my Samsung Nook tablet just fine. I haven't tried a heavy book with it yet, but would think it will hold just fine.
Adjustable metal side extenders- you need some type of lip/ledge on your tub for these to work. If your ledge is very shallow, I would recommend adding some type of rubber to improve the grip.
