So I use to have solar lights however they stop working over time. I decided to get these because of the reviewers. and they are perfect. we have had really bad rain and they've held up without water getting inside the bulb. They are every bright and just so easy to use. 10/10

I really liked this filter. I got this filter with the intention of the Solar eclipse that just occured. I am very happy that I got it and will be using again.

This is a must for anybody who is looking for a cheap 10 stop filter. I was skeptical at first given the price, but I have been pleased with my results. The images sometimes are a little bit warm, but nothing that can't be fixed quickly in post-processing. The surface also seems to stay clean and doesn't attract any particles.

Been using this filter for over 18 years and has kept my truck healthy...

These solar lights lasted about 18 hours on full brightness which exceeds the description. I left them on all night and had no problem with them. I received them quickly in proper packaging. The quality is excellent.

This 10 stop ND filter is great I use this filter every day

Pros:1) Retains image sharpness2) Warmer color cast (which I prefer)3) Higher contrast than Freewell4) Larger range ND range than Freewell5) Build quality better than Freewell6) Better carrying case than FreewellCons:1) Each ND stop does not have a hard stop or even a numeric indicator so you're not sure if you are on ND 8 or ND 16. This can be a con for some but for my use it is not a big deal as I primarily shoot video and use a monitor to gauge my exposure and just rotate the ND until exposure is correct.2) Filter does not have a hard stop when it reaches 400 ND and you can keep rotating it till you get the X pattern.I'm comparing this filter to Freewell ND mist version since that seems to be the most popular ND filter being used especially in the wedding videographer circles.In terms of overall build quality I want to say the K&F filter definitely feels a lot better. Even the overall packaging makes you feel like you bought a premium product. I really like the rubberized coating they use. It feels very premium and it has a good weight to it. The anodized orange indicator is nice and allows you to adjust the ND stop easily. The case that comes with K&F's filter is much more useable and compact compared to the bulky plastic cases that freewell gives. (There was a time thatfreewell's filters wouldn't even fit their case if you installed the magnetic cap which was a huge oversight on their part although I do wish K&F had a magnetic cap as well since those are the best IMO)I am primarily a video shooter and I was hoping that the filters would have similar color casts but unfortunately they don't. It's not hard to fix this in post but still would have been nice if they did match as I have multiple cameras. I do however prefer K&F's color cast as I tend to like warmer images. I also like the halation on this filter more than I do the freewell. If you look at the image where I put the two side by side the K&F is more contrasty and the light spread is kept where it should be and not across the entire image like how the freewell does it. This looks a lot more natural to my eyes. In terms of sharpness I could not see a distinct difference between the two. Both look excellent.Biggest gripe that I see other people having is the fact that there is no indicators on the filter aside from the first ND2 and ND400. The rest of the stops are indicated by dots. I don't know why manufacturers create an excellent product and then do these kinds of small short cuts. Although for me in real world use this probably wouldn't affect me, it did make testing the two different filters a pain. This is the reason why I have only included one comparison shot because I could only test the ND2 on both filters as that is the only two ranges that are clearly marked on both filters.At the end of the day in spite of some of it's shortcomings the filter does do an excellent job of what it is supposed to do. Cut light without messing with overall image sharpness or colors and give it that nice "cinematic" glow and I honestly think it does it better than Freewell. Thumbs up from me and will be using it at my next paid gig.

10/18/2022: I needed 2 of 6 solar landscaping lights replaced and replies was immediate and they took care of the replacement fast. I will have to see if all lights stand up well since I placed them out less than a month ago. For now, they look sturdy and nice enough.
