Advice for buying a new E-Rig for rosin.

i personally have a few different devices , however id probably buy another db e nail again if this one broke temp is adjustable from 100 to 1000 ,uses a unistyle nail aka it fits almost anything you want to put it on and as for cleaning just soak the nail or burn it clean.

Puffcos are great but there probably a bunch other great alternatives

Sorry I thought you meant a press. I have no idea about rigs.

A cheap, nasty option is a set of hair plate irons with a digital temperature option. Can spot them at second-hand stores frequently for 20 bucks.

Check honesysticks stuff. Also I am able to heat my rosin for a few hours at low temp (under 250f) and i put it in disposable carts with syringe and works pretty good. may need a slighly more powerful battery like 8w or so or whatever those disposable carts can handle. my liberty haze that was really terpy did really well in the carts because it was mor viscous than my other oil. nugsmasher has a tutorial on making carts from rosin. hash rosin should work a little better but my flwoer rosin smokes fine. not the biggest clouds in the world, but i like it it taste more like actual flower than all the added terps im used to in carts.
