The brand is fine - I have 2 of them tho not this model - and likely this model, though not their best by far, is okay too. If you can afford one of the better models then go for it. Most all models have canister adaptability.

The canisters are what I'll call moderately successful depending on what you store in them. They don't hold their seal indefinitely so aren't for long term storage and they aren't cheap either. We find there are much easier and better methods of long term dry storage.

I linked just some of the many previous discusions here on vacuum sealers for your review. Be sure to note the alternate sources for rolls and bags given in several of them.
