Review on Cutting plotter Brother ScanNCut CM300 by Kiril Gentschev ᠌

Bought the plotter in September. Everything is fine, I still use it, but there are a few unpleasant "buts". First, it does not have a Wi-Fi connection. On the one hand, there is nothing terrible in this, but on the other hand, I would like to have it for such money. Especially considering that the old model, which Brother discontinued, had Wi-fi, and it cost 5-10 thousand cheaper. Secondly, he has a very "walking" error. You can try to cut one circle 3 times, and 3 times it will be completely different. That is, in certain things where millimeter accuracy is needed. You have to calibrate the cutting template several times before you achieve any accuracy. Thirdly, perhaps this is a marriage, but in the upper right corner of the sheet and in the lower left corner on the A4 sheet, with exactly the same parameters, it cuts with a difference of several millimeters. Which once again requires precise calibration. Something like this. In general, the plotter is not bad, but it is very confused.
