Had a £13.99 import duty to pay to the post office in the uk, on top of the unit cost plus carriage and packing paid, so that made this toy rather expensive overall.
As a stand alone kit, the package works as advertised. Rather disappointed at the lack of instructions and I had not picked up on the need to solder components to the PCB from the original ad. You have to go online for assembly instructions.
I bought the kit to build into a larger project. Basic schematics and operating parameters would be useful to save guessing, after all, whoever builds this kit needs to be bit of a techie.
