not earl, but I have the travel ones. you re pack your stuff and roll them across the bed or a table to squeeze out the air. No vacuum needed on the travel ones. LOVE them! I can easily put a weeks worth of stuff into a carry on bag. no more waiting in line at the round up to get my bag. I take the largest carry on allowed, even if I dont use it, because if I pick up items on my trip I have room.
