After very fast delivery (as always by Amazon) I have made equal to the structure of the cajon. To assemble you need is a cordless screwdriver. Everything else is actually included. Tension belts, screwdriver, drill, glue, screws, sandpaper incl. Holder and and ... The construction is really easy, because all the parts are working very precisely and all the holes that must be drilled, are pre-drilled penciled respectively. When sanding should be careful on the corners, because the emery cloth is a little too rough. Otherwise everything was great! From the sound I am also very confident. The snare effect can be set and the bass is also very good effect. So all in all a buy rating with 5 stars.
