Yeah, the one that I had was a cheap piece of crap that only lasted a few years. I ordered it through the infommercial back then. And you might be right about the bags! You'd think that they would make those a little better to hold up against the rigors and torture of frozen food storage.
The thing just wasn't sealing the bags properly and lead to them losing the vacuum seal which was allowed to escape out and be replaced by dangerous damaging air. The main reason that I bought that unit in the first place was to help eliminate food spoilage in the freezer. But instead, it was contributing to the cause of spoilage!
And you're also right about Tilia not being the only vacuum sealer brand!
Rival also makes a vacuum bag sealer and the vacuum bags. Called Seal-A-Meal, this appliance was once made by Daisy in the early to mid '70s. It sealed the food in bags, but it didn't have the vacuum seal feature for them back then. I had one of those units.
I've always had a separate small deep freezer besides the one the fridge has. For many years! Everyone in my family has one. It's been a ritual that our moms and grandmother started when we were all home and growing up. It's also like having extra money in the bank.
And I've also had more than my share of foods and expensive meats drying out, getting freezer burn, spoiling and becoming pale-brown & rancid. Never thought that food could actually spoil in the freezer. But it can if it's not packaged properly! With my new Kenmore unit, this can now be avoided.
