Clamps smaller than the hose these were recommended for.  Too cheap to return to china.  Very cute little guys though!

Small springs do not have correct bends on the large bend end allowing that end to pull out of their hole. Had to match the bend exactly to the original springs to get them to hold position. As usual Chinese made = almost,  not quite exact or no matter.

hoses are way to short and to stiff I cut the s*** out of too older cases I had trying to make this junk work and ended up having to return it

While these clamps were recommended as an add-on to the 4" dust collection hose I purchased, please be aware THEY DO NOT FIT OVER 4" DUST COLLECTION HOSE!!!

I ordered two of these to put a UV filter into my pond fountain system.  First the pros.  A 1" hose fit on it quite well.  The adapter seemed sturdy, and that is about it.  Now the cons.  Others have said that the adapter will not fit well on a 1 1/2" hose.  I found out that it will not fit on a 3/4" hose.  Looking at the package it lists the minimum size as 20 mm which is slightly larger than 3/4", enough to keep the hose from sliding on without being permanently stretched.  The packages also appeared to have been opened despite the item being sold as new.  But after my experience with them I suspect they had been returned by another customer.  Overall I would recommend avoiding this product unless you have tried a few other options first and had them fail.

My F clamps don't fit...spaces are too narrow to accept the clamp.  I hope someone from shop fox reaches out with a replacement for me.

Inside diameter too small for 3/4 pvc. Returned because it didn't match description.

Slips on the hose clamps where other 5/16" tools work fine.  Very disappointing.  A friend brought a new one to work with a shorter shaft and so I shared my experience with him.  Later that day he was pissed off and trying to sell it to anybody who would look at it.  The next day he brought another new one from a different manufacturer.

False advertising!  These are cheap "Exhaust Mate" clamps made in China, despite the website description saying that are Walker brand; i returned this garbage

Not really suited for their intended purpose.  The problem is that they fit too loosely over the male fittings on the ends of 2.5-inch shop vac hoses.  I tried this with every 2.5-inch hose that I have, and found that, in every case, the hoses keep disconnecting from these couplers with the slightest motion or tug on the hoses, for instance, while vacuuming my garage floor.  Don't waste your time with these.

These did not work as expected.
They feature a threaded bar with a locking nut to adjust their expanded length, which is impractical at best. Moving the locking nut down the length of the threaded bar is nearly impossible and a regular nut would have been a much better choice. The difficulty associated with adjusting the clamping length is so severe that as yet I have been unable to test them with proper adjustment, but even at their furthest extension they don't span the gap between my trailer tires.

MEASURE YOUR GAP FIRST. These are exceptionally small.

These are cheap, overseas made clamps. None of the package received actually worked. The rivets that hold these together was not fully seated. I took them to my shop and beat the rivets with a ballpein hammer.  This closed the camlock sides and made these usuable.  They are cheap but you should at least drive the rivets all the way to make a useable product.

These clamps do not fit the Polaris 380 or 280 hose.  They are about the size of a dime; much too small to be of any use.  Maybe these clamps are for some other purpose but if you order them to clamp hose connections or to clamp the hose to the wall fitting, they will not fit.

These are really small and I probably missed it in the description but for a lawn mower or a small trailer not for the travel trailer in which they were bought.  Atleast they were cheap!

The hoses are the lowest quality possible, and way too short to do much with.
Mine didn't come with the adapter to smaller hose.

Bought this and a HDMI to VGA adapter both recommended by Amazon. The screws to secure this cable into the adapter are way too short. Probably too short for a lot of uses. Had to use rubber bands to secure the cable around the adapter.
