Works fine the first few times, then loses its functionality -- unable to keep seal.

The containers are nice, but not pleased with how this is advertised. The title says "bags", the listing has images of bags, but only containers show up. Upon closer reading, it does not include bags, but any reasonable person would be confused by this.

Electric pump is weak when use it with the glass container.

not sure if it is just my unit, but the pump sometimes turns on by itself when sitting in the up right position.

The mid size container would not seal, phoned and was told it only came as a set so sent replacement, which turned out to be a bit smaller and did not have valve for pump

A good idea, very sensitive on off switch. has very low and slow sucking power
