got this for christmas a couple years back and i hated it the first time i used it. i thought “no problem its just a weird design and you have to learn to use it.” I STILL HATE IT. worst design ever. if the bag is too short, you have to hold it while it vacuum/seals it. didnt seal properly? that sucks. you have to do the whole vacuum again instead of just the sealing part. i hate this design so much and want a different one so badly. DONT GET THIS ONE.
