Worked exactly how it was meant for, no air in mattress so no slushing sounds.

Arrived on time as shown in picture.

Does not work. I had to burp my waterbed manually as I have done in the past. This tool does fit in the valve properly but did not work with burping the bed. Will be returning this item. Thanks

You sold me a piece of junk that doesn't work, and you want to charge me 50% of the purchase price to return it. I won't be shopping at wayfair again.

Exactly what I was looking for. Hard to find, but super easy to get the air out of your waterbed with this super burper. Received within 2 days of purchase.
