Vacuum works well but product needs work
Pros - works really well to reduce bulk in duvets/blankets
Cons - I bought 3. One one, one side of the strap wasn't sewn in properly so came out. The tote ripped on another because the handles are really not strong enough to hold the weight of several duvets; the tote really needs to be lifted like a box. (I didn't bother to return but am sure exchange would not be an issue).
A cheaper and more effective option I have used is to buy the vacuum bags without the tote. You can squeeze a few duvets into one of the original bags the duvet/blanket came in. I've found those bags work well; you can use the handles.
