Answered in the other topic but in case anyone else was wondering, I'll paste it here too.
I think I preferred the Devil Press bags over the others I've tried. I'm stretching my memory now but I have a vague recollection that the squish-it bags would blow out before hitting optimum pressure, but then I was fairly new to the rosin game so could well have been me doing something wrong like too much pressure too quickly. I'm currently using Rosin Tech Products "ultra sonically sealed" that have no sewn seem. The rosin can't get caught up in the stitching but I've found that the sealed edge is the first place to blow and happens with a little less pressure than the Devil Press bags so caution is required. I think you can still get the Devil Press ones on Ebay and other places online. I bought the RTP bags I have now from their EU website along with some other bits. When they're gone I THINK I'll go back to Devil Press myself but may change my mind towards the end if the learning curve.
