Update:I found this on another one of their storefronts nowhere near the markup found here. The price was reasonable and what anyone would normally expect for this type of item. I ordered from there to have a spare and after it was complete, a day later they send me an email saying that this flex plate was "not in stock". Even though there were many pieces listed as available. The order was cancelled. A day or two later I find that the plate is re-listed but $74 dollars (tax, shipping, etc). Now I know why it really "wasn't in stock". That kind of business practice is unacceptable. Lastly, in testing I had to cut a perfectly good spare mag sticker since the magnet they sent could not be used. I didn't get this to only use half of it so its being returned. I ended up getting a custom cut spring metal piece less than $25 shipped. It's worked perfectly ever since.I have the Mighty 8k from Phrozen and as with all my printers I have flex plates on them. There aren't many companies that have this product as of yet for this printer but Antinsky does. As another reviewer stated, the included magnet is way too thick at over 4mm for the mini or the mighty series resin printers. There is absolutely no reason to have a magnet this thick included with the flex plate. A 2mm would have sufficed.The other issue I have with this flex plate is how round the edges are. Antinsky, you engineered these flex plates but fail to accurately cover the entire bed so that your product looks uniform with the build plate? It looks odd. Lastly, the plate has one smooth and one textured side. Be aware that the textured side will show should you print an object flat. Should not be an issue in many cases but be aware. For the price as it stands right now almost $58 I am thinking of whether or not to return it.
