Used it to look for AC leaks, works good and is pretty UV reactive.

I've had this film on my south-facing windows for several months now and can see the difference in my electric bill. This stuff works very well at UV and IR filtering and is easy to apply. It looks very good when applied properly too. Just use lots of soapy water on the film and the window when positioning the film and you'll have a fair amount of time to work the bubbles and edges out.

I'll be ordering more to take care of the west-facing windows, which can get a lot of sun in the SoCal summer.

It's UV protection, plus it protects your lens.

This shade is good for the price. I don't know that I really trust that it is giving any UV-protection but it does work well to block the sun in my child's face and out of her eyes which keeps her happier in the back seat. I didn't have may issues with attaching it (rolling window down and hooking on window) but it does make a little rattling, which isn't that noticeable. I was hoping to also use it in my husband's truck but really couldn't find a way to make it work because of its size. I works fine in my SVU. Overall serves the purpose for the price.

Works really good and I am very pleased.  I use this for my sunglasses which have a metal frame.  I will be looking for plastic frames soon, my glasses frame get too hot on dash.  Good price.

Easier to apply and wipe off than most other waxes/sealants.  Odor isn't bad and it does a good job of protecting for a good month with 2-3 washes in between.  Haven't gone longer than that, but the water still beads up after a wash/rain. I also use this on my headlights to protect them from damaging UV rays and help keep the headlights from oxidizing and turning yellow.

Bought for air conditioning leak detection with UV dye and it wirks VERY well. Much better than the little pen lights for the same price at the car parts stores. Kinda hard to photograph, but very easy to see dye and tell it apart from corrosion or other things that glow a little.

Inexpensive, but pretty good bargain overall. Worth the price for the UV filter alone!

This works good. Photo quality is good. I wish I could install a protective UV filter on it. I caulked one on.

I use this light as tour guide in a cave with formations that happens to fluoresce beautifully under UV. I had been using one from Walmart, it looked OK but the would break in about a month. This one is not much more expensive but it is much brighter and looks great. I was afraid this one would not last long either, it doesn't feel very solid but so far so good and I've even dropped it down a shaft, OK it was in a drag bag at the time but it made the trip just fine. The next step is a battery powered UV light with different wavelengths for a reasonable price, just saying, in case someone is in the mood to develop one.

Nice UV LED light. Solution is fairly liquid, flows nicely, gotta keep it in control. Remember, it's not a glue, but a surface bonding agent. So far, many uses around the house, especially for small projects and repairs.

Does a decent job of blocking sun. Put a uv bead under it and it worked well at blocking uv. Band is a tad tight, could use an adjustment mechanism. Gives a slight headache if worn too long.

I like it. I've used UV air treatment in other systems.

I use UV 365nm for skin examinations looking for fungal infections -- many many LED UV sources emit 365nm light, but also radiate a lot of light in lower wavelengths making it hard to see faint fluorescence from the infection.  The light from Ozzy Paws is much cleaner, plenty of 365nm with less pollution from other frequencies.  Solid, pocketable and the price is right.  I checked out a $1000 LED Wood's light from a medical supplier a few years ago -- Ozzy Paws spanks it.  Nice product.

I've never really noticed UV interference or anything of the type; all I got this cap for was protection. It's made in the USA (says right on the side), it's metal, and it's well built. I did not notice any picture quality degradation, which was my biggest concern. It screws right on, and I doubt I will ever take it off (unless someone breaks the glass on it or something). It's not multi-coated, but it gets the job done just fine.

The UV light arrived in a timely fashion, was packaged well, and was in perfect condition. Sturdy construction. It came with batteries so I put them in and started wandering around inside and outside the house, shining it everywhere. It shows up so many things that are invisible with standard light. Of course it works better in the evening or in a partially darkened room. It actually works better than expected. So far , I am very satisfied with this product and would recommend it to others.

Works as intended to protect my camera lens and blocks UV light.
