A steel sheet and PEI sheet were not included in the package. After opening a dispute, the seller sent the rest of items. The steel sheet arrived in a bad condition
It all looks good but for example the spring steel sheet is not really spring steel and the aluminium PCB plate is totally warped, like a few centimeters across. This gets somewhat leveled out by mounting it on the Y-carriage but it's still bad. When I confronted the seller with the spring steel sheet not being real spring steel they asked me for a photo. I guess you can't really tell from a photo. If you really have to buy this kit just really don't bend the sheet because it will deform and never return to it's original shape. In the end it was a waste of money. It looks like a nice kit but these defects show that the producer has not taken the effort to get the finishing touches in. I will update this review after I have been using it for a while if it's possible. I would never buy anything at this shop again, my other order was sent to the wrong address and the seller has never replied to my messages. Luckily the Aliexpress was so kind to do a refund, for which I am very grateful.
Oh and by the way, the screws that come with the heated bed also didn't fit, the heads would not fall into the countersunk holes and they would stick out a little bit. I had to order another batch of screws with the correct sizes to fit the heatbed on the Y-carriage.
