These caps work great. We've only has them installed for a couple of weeks but we haven't had any issues with them so far.

They work great. Only issue is the plastic caps keep falling off so I just took them off. The spreader bar would be better if a wrench wasn't needed where it connects to forks. Something similar to the handle where you set length of spreader would be great. They do work great though.

These lens caps work as well as any camera label caps on the market and they are very inexpensive.  Four caps should last me for ten years.

These caps are easy to put on and crimp in place. They give your job a 'finished' look, plus, the shift cable ends don't fray and come un-wound.

They are only ok. One of the original caps poped out so I bought those as a replacement. The first two poped out within a week... I keep them in the trunk just in case - but they aren't all good...

These caps are great quality and I only replace them when I grease the bearings.  I use them on my RV, Boat and Cargo trailers

I mean, they are valve-stem caps, so there's not much to review here, but I did want to note that not only are these a perfect OEM replacement for recent cars with TPMS sensors in the wheels, but that they can still be used on older cars without TPMS sensors. The newer valve-stems are thicker (diameter is larger) at the base and then they taper towards the end to reveal a narrower threaded portion.  The caps thread on and cover the metal taper, so everything looks seamless.  On older (non-TPMS) valves, which are a consistent (smaller) diameter from beginning to end, with no taper, these caps thread on and the "skirt" of the cap that goes over the taper on the newer stems just goes over the rubber portion of the existing stem.

In other words, if you have both older and newer cars and are trying to decide which caps to get, these will work for both.

I lost one of the original OEM silver valve stem caps on my pickup. I replaced all four so they matched. The caps screwed on with no problem and look good. I would recommend these to a friend.

The caps are a little hard to snap off, but overall a great product.

We are very happy with these hubcaps.  They are plain, without branding, but costs much less than the "real" thing.  They were easy to install and we are happy with the look.

Purchased these caps to replace the caps that came with my Sigma lenses, which are very difficult to get on. These work excellent, as I was informed from some source I can't remember. Excellent product!

The lens cap(s) work great. I have one replacing the Nikon cap that did not have a securing line and was lost. I also have a spare just in case.

These work great.  As others mention there is a venting hole in the cap, so don't turn them upside down. They hold enough for us and shoot 10-15' while being easy enough for 3 to 4 year olds to use too!

It's really nice to have simple gas can caps that actually work the way caps worked when I was a kid. Used these to replace the EPA mandated crap that come on new plastic fuel cans these days. The bill-of-material "safety" caps must have been designed by an idiot because they simply don't work, but do result in significant fuel spillage. These are great replacements along with a few simple funnels.

These are great caps.
I often give caps away as ad specialties. This is a little expensive for that.
However, for my cap, this is my first choice.

If you're going to get a logo put on a cap, this is the way to go.

Great construction.

These work great with Rust-Oleum cans, I only use NY fat and ironlak skinny caps with the adapter not sure how they do with other caps.

The only reason I didn't give this 5 stars is because I called a while ago asking for new caps since ours broke and we have yet to see them (it's been months).
