I am percussionist for 7 years now and I've never tried to play a cajon because I never had a need to play this instrument, but I wanted to give it a try.
It was packed in one cardboard box and in that box, there was my cajon in its bag. After I tried it for the first time I heard a weird sound, so I decided to use some tape to tape the strings to the playing surface, and it helped. If you have the same problem, you know how to fix it now ;)
I have used this cajon in some gigs, and also when playing in some home parties, and they said that the sound that was coming out of this box was great. I also think that the sound is good, for this price you can't really expect much more.
Pros(+):
Cheap,
Good sound,
Comfortable to play for longer sessions,
Bag included,
Looks better than cajon who is all in one color.
Cons(-):
The sound without fixing the strings to playing surface with tape.
I bought this as my first cajon, and I can say that it was worth it.
