That looks pretty heavy duty.
Does it saying anything about cool down times? I know on my sealer, after 5-7 seals or so, I have to let it cool down for a few minutes before I can use it again.
I know the higher end models do not require any cool down times.
For my typical needs, this is not a big deal, but if I have 25-50 pounds of pepper stix to seal up, it is a pain in the butt to wait for the cool down every few bags.
