I am not a cajon player, but my friend who plays percussion doesn't have an Amazon account, so I bought it for him. Now with "social distancing" we have to wait until we play together! So I am going to write the review from my point of view.My Donner cajon is the full size one, measuring 12 x 12 x 18 height counting the rubber feet. When it is not being used, it can become a side “table” to place a recorder or other electronic equipment. The hole allows you to place some things like papers, etc inside the unit for transport. I would be careful not to put something hard so the snares (see below) get damaged.The cajon comes with a nice black carrying backpack, with good all side protection and bottom reinforcement pads, solid backpack straps, a top handle and a zippered pocket 12 x 10 x 1.5 in. to carry accessories, papers etc. The cajon itself is light (9 pounds), with solid supporting sides and well made, with an attractive finish (clear in my case). It is well put together, with nice rounding edges and tight joints. Four solid rubber feet isolate the cajon to improve the sound. The front sounding board or "tapa" (tah pah) seems to be birch, and it is well secured to the supporting walls by 16 removable screws.After watching a couple of videos, I could get different sounds out of the cajon. The volume is more than adequate to accompany acoustic guitars, etc. This being the larger size cajon, the bass depth is pretty good. The cajon has 2 internal snares (similar to guitar strings) placed close to the internal side of the tapa, each snare shaped like an "A" shape. The top the “A” for each snare is fixed somewhat to the top of the inside of the tapa and the A legs for both snares go to a wood piece that can be adjusted - via 2 hex screws in the bottom of the cajon - to "tune" the snares. Inside, there is a holder for the hex wrench which comes included with the cajon.Additionally, on the inside of the tapa, there are two velcro strips that can be positioned to adjust the "muting" of the snares, letting you go from a drier sound similar to a conga drum to one more similar to a snare drum.Comparing prices, I only saw one unit with a lower price, from a brand not known for its quality. The higher prices could be up to two and half times more than this unit.All in all, the Donner cajon is a well made unit, with a very good sound, accessories and a very reasonable price.
