Before you buy this particular model I suggest you do research and find a cajon with the sound you want; it definitely isn't a cheap purchase. However if you like the sound of this particular model then I would definitely recommend it. The build quality is very good, and even under my hefty weight the box feels sturdy and strong, even whilst leaning back. The snares are very quick and easy to apply/remove and don't rattle when disengaged. It's loud enough for an acoustic guitar or piano, but if you are amplifying then the soundhole in the back is big enough to drop a microphone in should you wish.
In conclusion, if you're not sure which cajon you want then go and do some research, watch some videos, listen to some models etc. However if you're thinking of this one then I'd heartily recommend it.
