10/10 Would Buy Again
Size: Large-3SET
Absolutely gorgeous cutting boards. Bamboo is a rich deep drown, sturdy with all sorts of foods - vegetables, meats, fruit etc. Nothing sticks and very easy to hand wash - makes food prep a breeze. Great value, size as described, easy storage upright for drying.

Great quality for price
Size: Large-3SET
A little on the thin side, but it’s made with sustainable bamboo, and is nice to work with. Just don’t ever ever let a bamboo board like this stay wet for a long time. It WILL absolutely warp/de-laminate.

Great chopping board and very stylish, look great with modern home
Very stylish and looks really lovely on the kitchen island. Been using it for over 3 months.
only little complain I had is that I wish they do a better job cleaning up the back of the board, there are some wood spike that aren't fully smooth out.

low quality; not as advertised
Low quality. The wood has an unpleasant smell, even after initial washing and thorough drying followed by extensive seasoning. Several of the surfaces of the boards were rough. One board was gouged on the bottom (I typically use both sides of the cutting board). Another board had a small amount of wood filler on the bottom. I was forced to sand most of the surfaces in order to smooth them before I seasoned them.
There are gaps in the stand where boards join that are not filled.
The boards are purported to be pre-oiled, but I didn't see any evidence of that.
The "detachable non-slip rubber feet" are not attached and are a little too hard to be "non-slip". If you want to attach the feet then you are on your own - there are no pilot holes and the screws are not self-tapping. The screws have a conical, tapered head and so they do not match well to the feet - a washer-head screw would be the correct type of fit.
Lastly, I don't know my wood types that well, but furniture and cutting board acacia is said to be significantly harder than oak. These cutting boards do not strike me as being as hard as my old oak cutting board.
