After many failed counter top food saver type sealers I decided to finally get a chamber sealer, and I am not disappointed! After looking at many online I just couldn’t pull the trigger on a $1000+ sealer, then I found this one and watched YouTube reviews and for under $400 I just couldn’t resist! I sealed a block of cream cheese, an empty can, a bag of water, and finally about 3 lbs of burger just to run it through the tests. I was more than happy and the seal is perfect! I did not use the oil that came with it after bad reviews on the oil, so I purchased the good stuff on Amazon and after filling the unit I have enough left over for probably 5 years! I do a lot of sausage making and buying meat in bulk, so this will be perfect!
