Query: Horrible!

Horrible! Does not fit the Sentria like the description states. Looked like it would work but ended up with a huge mess inside the bag! Thought I'd try it again and again the bag came off of the hose. I had to resort to duct taping it just for it to work until we get new ones. Do not waste your money! If you have a Sentria do not purchase these! You will have a huge mess on your hands!
