Came in very handy
I'm just finishing my new shop and needed these to finishing installing my dust collection. They are good quality and they do the job. Fit is good with other product lines. Thanks

Works as expected
Fits both 4" and 2.5" flexible hoses for dust collection well. Maybe a bit over priced IMHO.

Perfect fit and durable
This fits perfectly into my 2-1/4" preformed hose end to use my dust collector on my bandsaw. It's held up well, removing it many times.

Have bought many of these
These were great! They make it easy to connect pipes or connectors for dust or ventilation systems. They fit nicely around 4" connectors, and you don't have to force them on.

Very useful
Bought two of these. One for router, other for Compound Miter.

Mine did not fit my router base at all, and I was stuck with it.
All was as expected until, after following all directions, it would not fit my Bosch RA1161 base. Hoses fit together, and all else is okay, however if it cannot fit the router base, it is of no use. I had to download and 3d print another dust collector. In design, must can be improved. Adapters are a tight fit, as though the idea was put together with pre-existing pieces. I ended up replacing everything but the wye fitting and the hoses in order to get a really good fit. Well, to keep the cost down, I guess it was necessary.

I have a fairly new Skil router / table combo and this doesn’t fit my router at all. Not even close. The tubing is way too stiff. I’m not happy with this set-up at all. Will be returning for refund, sadly.
