This product was sent to me for review, as part of Amazon Vine. The below is my own real-world experience of using it.

I was drawn to it, because I occasionally like to shoot wildlife videos with my iPhone 15 Pro Max, and thought that the filter would be most helpful during very sunny days.

The kit is comprehensive - you are getting the magnetic filter attachment, the filter, a cleaning cloth and an exceptionally good-quality case to store everything inside. This itself is compact, so would easily fit inside a small bag.

I have mixed feelings about some of the components - the main filter attachment is robust, but doesn't fit well over a case. The one I use is not the thickest, but it was enough to impede the attachment from lining up properly with my phone's lenses. I also don't like the screw clamp - the idea of putting pressure on my phone's screen makes me uncomfortable, especially because you can tighten the screw quite a bit. The magnet works fairly well to hold the filter, though it didn't seem like it had the strongest of holds, so I am unsure for how long the filter could reasonably be held in place, particularly if you are moving around a lot in the field.

Despite the above, the filter itself does make a difference in harsh light, though I would recommend checking some settings first - I didn't realise that my flash was set to 'auto', so it fired underneath the filter, and washed my first attempt at a picture out (the flash is obscured underneath the filter, so the light is bounced back).

Overall, it is a nice kit, but could be improved.

This particular light is really neat. It has multiple functions that I find useful, which includes the telescopic function and the magnetic base. The light also has a mini 4 legged base that can be staked to the ground on a windy day. The telescopic function works well and I like that the light can be flipped to be used as a flashlight or used as a lantern. Also impressed by the Bluetooth speaker. The light itself has 3 color temperature levels that can be changed via pressing the light button and the light can be switched from colder tones of white to a warm tone that is almost an orange, and you can adjust the brightness by holding the light button. The designer of this light must've put allot of thought into how to pack so many functions into one light.

now have 6 lamps with almost identical function and size to this lamp, so I will refer to my experiences with those lamps for comparison. This is a small battery LED (bi-color and fully RGB) with probably the coolest design of all the lights I have, and very simple operating modes. This version of the light is stealth black on black on the back so if someone tries to use it the first time it's hard to read what each button does, but it looks cool and doesn't have the bright white paint if that happens in the picture. I would like the scrolling of the buttons to provide faster action (e.g. it takes a while to scroll to 100% or to 1%) and I feel like the brightness isn't as strong as some of my other similar lamps, but the color temperature measures very accurately and the battery seems to last very well. I have pictured the LEDs at 4000K with 1% brightness to show the number of LEDs and arrangement. I've owned MANY K&F products over the years, including tons of ND and VND filters, tripods, etc., and these lights fit the same high-end build quality as the other K&F products. There are two magenta on the back that you can slightly see through the transparent back. They hold REALLY well on nice flat metal surfaces, but even on a round post they can hold if placed properly. It comes with 1/4 20 screw holes on the top and bottom, and a 1/4 20 cold shoe holder is included. It's worth noting that there is no cold shoe slot built into the lamp itself (for stacking lamps), so you'll need a 1/4 20 to 1/4 20 screw to connect two together. Not a deal breaker, but I often plug my lights in during storage to keep them all together. The overall performance is great, and the build quality and style (if that matters) can't be beat. These are beautiful lights!

This is not my first video light, and I’m sure this is a good video light. Color of RGB can be changed easily and the battery last relatively long, at least 2 hours as I tested. Will buy the second one if needed.

As someone who makes YouTube videos, I’ve accumulated a lot of little RGB lights over the years, but this is by far the coolest, I’ve seen. The overall design is similar to what you’re used to in that it has a CCT mode, RGB mode and some pre-set scene modes, but it’s the overall execution of how these are employed that really sets this little light apart from the others. The style is quirky and cool. It comes in a package that literally looks like a box of tofu. And where others would have boring buttons or sliders, this light uses giant knobs on the side have a fun retro-modern kind of vibe that actually work just as good as they look. From the bottom knob, you can switch it on, turn to CCT mode, RGB mode or the scene modes. The top button allows you to change the intensity of the settings in the various modes, i.e.: brightness, saturation, etc. And of course there’s a magnetic back and not one, but two tripod mounts - one on the bottom and one on the top. This is a really well-designed little RGB light that stands out in a crowded market place of similar lights. This light both looks great and works great - definitely would recommend.

Very good. It polarizes properly, easy to cut out and glue onto the light bulb and there is plenty left over (after cutting out what is required for a medium sized bulb that I use with my mobile phone). They are two sheets, slightly smaller than the size of a sheet, covered in protective plastic that must be removed before use.

It's perfect for my LED bulb, just cut out the sheet a little and it's perfect

The 1/4 Black Mist Diffusion Filter from "K&F Concept" (never heard of) arrives at home well protected in a filter box. I ordered this filter for my Canon FD 50/1.4 ssc (filter diameter 55mm) and what I noticed right away was that the filter hesitates when I try to screw it on....this can then be a bit of a game of patience, but you have it sometimes once the start of the thread is caught, it can be screwed on without any further problems. The image quality is not negatively affected by the filter, it just becomes a bit softer (dreamier), mainly when light is involved. I could still show pictures of my daughter (from my hobby studio) with light from behind, but you're not allowed to anymore. I think you can see what the filter does from the two pictures I posted. If it weren't for the fumbling to screw it on, he would have gotten all 5 from me, so it's still a very good 4.
