Devices wise I would say your safe to use anything with distillate
Depending on your preference 5-10%terps is the range people stick to higher terpene content means it will be more flavor full and a little bit more viscose more runny
(distillate isn't too thick and it's easily heated so most carts or devices handle it pretty well)
With shatter it's one of the thickest concerntrates along with budder so you need to decarboxylate it to completion and possibly add terps just to be safe if it's your first go yk just to be safe
But 50% distillate along with 50% of just about any concerntrate should work with just about any device don't hold me to that
Most devices are a one and done and should not be RE filled a lot of people in the device game frown upon 3ml-10 ml devices cause the flavour goes and the coil burns for the most enjoyable experience fill it once and use it till it's empty
Any little query's or questions feel free to lmk bro
