Growhealthy Rosin Carts

Is anyone else having trouble with these? I like their rosin but i've had to exchange carts many times and half the time the exchange one i receive has the same issue after a few puffs. I don't let it get too hot, lowest battery heat setting, but i swear they either leak from the bottom or get a burnt taste and stop vaporizing before i even get through half of it. so much wasted $, does anyone have recommendations for other rosin vapes that maybe don't do that?
