Do not recall if these machines were available when I began concentrates. I just use a 10 Ton Dab Press, works well, can be a lot a fricken work compared to a all in one machine. There are so many variables involved with smashing, they seem to get more complicated with home grown weed. Sum cultivars just will not press well which cuts into your return. I'll stop now,I could go for longtime talking smashing, sorry. I should not put anything foreign into my lungs due to medical reasons , edibles have more than fill that void. I'm so deep into pressing now I don't think I could change, but the ease sounds so good especially if you can really dial in your concentrates.
