I found this well engineered crevice tool to be very handy and easy to use. It's long handle means No Bending Over and this feature also makes this tool "miles ahead" of competing tools. I am very pleased with this tool(s) ease-of-use and I am happy to own it...
This Flosser worked great on my Trex deck, which has a tendency to collect wet leaves and small seed pods in the spaces between the boards. Use it with a hand held leaf blower like a Worx battery model and you can clean your deck in no time. It does have a sharp blade so be careful.
I highly recommend this one.
At first I thought the flosser was too expensive, but it is well made and has a lifetime warrantee. It is easy to use and gets the job done quickly. Just what I needed.
