Seems to fit together well and fits my WG545 just fine. I’ll use it to blow off the slides on my 5th wheel trailer. Hoping it will work even if the leaves are wet. Looks like plenty of power with all the extensions for what I need. I’m ok with the materials it is made out of, i.e. looks sturdy enough.

Bought this on sale in February. Took it out for first time to blow all the falling seeds from spring and due to a storm so bad it caused a dust storm in Chicago. At the time I bought it, the description said compatible with WG585. The instructions say it is compatible with WG585. It is NOT compatible. Something I’m sure they found out because the description has been corrected.UPDATE: submitted an email to customer service on Saturday. Got a response back asking for detail contact information that same day. Two days later I received an email confirming they had the right order number. And by Thursday I have a pending refund to my CC. Updated from one to three stars. In reality my rating is more about being disappointed that it wasn’t compatible to my model because the design (mimicking the same locking design used by the native air volume adjustment attachment) and quality of the interlocking pieces (they seemed to fit tightly together) leave me bummed I can’t use it. Here’s hoping they make one for the wider nozzle of the WG585.

Great product, however it always wants to rotate which is a pain

Works decently, but it's missing the universal adapter. I received a replacement product, which was also missing the adapter.

Not vey sturdy. Cheap plastic . Once attached to blower I can not get it disconnected.Doesn’t work very well with wet leaves. Did an ok job on dry leaves.
