Solid, tight with a quality annodization. No instructions, however, if you YouTube the Tecre machine there are several great instructional videos available. (when inserting the dies, make sure that the vertical metal bars on each lower die are positioned towards the middle of the unit)Purchased from seller "Mophorn" who shipped and answered questions promptly. Only worrisome point now is where to find button parts. Most domestic sellers specify that their parts only work in USA built machines. The design of this unit is quite similar to the Tecre (American brand) but it is the internal die dimensions which ultimately determine compatibility. Besides the fact that the button backs provided in the kit are plastic. I have placed an order with a company called "Buttonmakers.com" (100 sets of 1-3/4" Pinned metal Back Buttons) and hope to trial them by the middle of May 2019. More to come.........5/5/19 UPDATE - Being unable to make more buttons on this machine than the limited number of starter parts provided, I purchased a quantity of steel backed 1.75" (44mm) button parts from ButtonMakers.com. [NO PROMOTION IS GIVEN HERE FOR THAT COMPANY ONLY THAT THEIR PARTS CAN BE MADE TO WORK] The steel pin backs are roughly 1/2 the thickness of the Mophorn plastic backs. Solution to using them in a Mophorn machine is to remove the pin from the back from one part. Place the back into the bottom of the die as shown in the photo. This becomes a spacer which makes the bottom die just the right height to function. Now just run your button making process as per normal and voila! You've got steel backed buttons and parts that are readily available. I have not tried any other supplier but my guess is that the end result will be the same.
