Great product. Fast charge. Saves tons of vacuuming. Always on edge of pool when finished for easy removal. Corded handle is nice. Can't go wrong!

These are easy to use, I replaced the pin on my lawn tractor wagon with this for the locking function... I was so tired of looking for the stupid pin whenever it was not replaced immediately, or when it bounced out. They also work great on my trailer hitch, when I take it off to remove my trailer I have a spot I lock it on so it never goes missing, and I keep a couple of these in my tractor "glove box" so I have replacements in the field; these aren't likely to wiggle loose.Great price and good quantity.

These hitch pins seem well made and easy to use. I have a small travel trailer and a utility trailer that these will be used for. Nice to be able to buy in bulk for a substantial discount in comparison to buying separately. Having extras on hand in case of an emergency or loss is great. They do offer these in different sizes and in silver or gold colors. Very pleased with these and the asking price for them is a true bargain. 5 âï¸â€˜s

I have a few small trailers that use the 1 7/8 ball. These pins fit perfectly and now I have a few spare in case I lose one. My boat trailer, Quad Trailer, and yard waste trailer all need the same size and I have been moving it to the one I need each time. Now I can just put one on each and have a few spare, just in case. they fit great, and the latch is not to stiff to make it difficult to use.

These pins are nice and fit any receiver. I'm not sure how or why, but I can't ever seem to be able to keep up with my pins. Now I have plenty of extras for whenever the need may arise.
