Haven’t actually stamped with them yet but I don’t see why I’d have any issues. They seem to be made of strong, hard plastic and be durable. They look like they are 3D Printed, which isn’t a bad thing, it’s good. These are unique items and a smart idea. If you are looking for a cheaper alternative to store a mnemonic all you need is these, some washers and a nut and bolt and a stamp kit. You could find a place to bolt them like inside of bed frame or truss in the attic are a few ideas. You can even buy nice fire proof titanium washers if you needed.

the shell came fast. The quality is great all the pieces fit together seemlessly. it’s freakin awesome, even the box it comes in is great. And they give you 2 stickers. I really enjoy building these nodes and can see myself ordering another shell. Keep up the great work! ⚡️⚡️⚡️?

Very satisfied with this product, shipping was faster than expected!

A 24mm stainless steel washer is too small for these – they fall right through the jig’s hole. The quality of the jig itself is fine, but don’t look for 24mm washers. You’ll need slightly larger ones.

So nice, I had to buy it twice. In sincerity, now that the first one had been running for a while, I really like these devices. Easy setup, set and forget. Consistent hash rate and clean package. The web interface is limited, but this is more geared towards the everyday user.

Buy these whenever you see them in stock! Great hashrate for the price.
