I have the Tilia Vac 800, pretty basic model with the jar seal feature. I love it and it serves all my needs. 90% of my use is with the bags, the other 10% is used with mason jars and canisters. I love mine, but the only thing I don't like about it is that when sealing, you have to push on both sides of the sealer to start the seal process and complete it. Takes a bit of effort!!
