The goods came. I have not checked the performance yet. I will add feedback as I gather. The goods were poorly tracked. The goods went a little more than a month.

took five hours to build, fun to use and program. no missing parts, be sure to use a video of how to build, because there are no instructions included. 6gram servos, so not super strong, but works fine and uses little power (less than 500 Milli amps with one moter moving at a time)

Comes with a BP with a Type A plug, which is not suitable in Russia. On the site of the store it is not specified. The manipulator is quite complex in tuning, and the problems are not so much in the assembly of acrylic, but in setting zero positions of engines. Acrylic fragile, drag the screws-crack. There are several mismatched holes in the base. In general, it will be necessary. Thanks to the seller-the software is already flooded. Collected and earned. If you are not friends with mechanics-do not buy. But the manipulator is excellent for such money!! For a child the most that would make friends with cybernetics)) I recommend, but with a look.

it is a fun build, and i recommend it for teenagers or grownups. unfortunately, it's seems like the servo engines you get with this are not strong enough for the main arm. other than that, the instructions can improve, and engineering of the base is must improve (everything is standing on one small acrylic piece and two nuts).

Received the order at indicated date as when ordering. Pity that they shipped the power supply with the wrong pins ( US or UK instead of EU). Complaint was dealt with swiftly and received a partial payback as requested. Product complete and was well packed.
