The filter is really good, it seems to be a real 10 stop filter (some ND1000 are only 8-9 stops, which makes shutterspeed calculations hard), it is reducing light in both Visible and Infrared light (has been tested on a full spectrum camera used for Infrared Photography), so you will not have a nasty discolouration in the sky as with other ND filters, but you will get a slight blue colour cast, nothing that can not be fixed in post process with the white balance tool, but I highly recommend doing a white balance setting with the filter on to get accurate colours, especially if you are shooting in JPG. I did not see any reduction in detail (see the 100% or 1:1 crop). It easily screwed on my lens and step up rings as well. It has a nice grippy area which I find giving a much better grip than other filters. One thing I'd like to mention is the case it's coming with has a nice locking mechanism and also two carve outs to be able to easily remove the filter from it's case, actually it's one of the best cases I've seen, beating the nice metallic cases from Gobe, which does not close well with larger filters.
If colour cast is a critical issue for you then this filter might disappoint you with it's blue cast, in that case I recommend Haida's NanoPRO ND1000, which I unfortantely lost, but that has virtually no colour cast at all, but nearly triple the price.

The 10,000mAh rechargeable battery is a powerhouse, supporting up to 7 hours of continuous work. This, coupled with a 1/3 CMOS high-resolution sensor, ensures that inspections in low-light conditions are clear and effective.

The filter quality seems to be perfect. I'm used to that from K&F Concept. And you get a really nice blue streak effect. The problem, however, is that you get that with every single light source in your image, so you don't really have the ability to be selective. You have to compose your recording really carefully. The filter rotates smoothly, allowing you to change the direction of the stripes, but you'll still see them in any light source. I think in the end Photoshop is probably the better option to give you more control over such effects. Still, it's a worthwhile tool to have in your toolbox, especially given the cheap price for an FX filter. It uses the same high quality optical glass as the other newer filters. The precision machining of the filter threads and ring is impressive and gives the feel of a much more expensive filter. So I can't fault any of the properties of the filter. It's just for the way I shoot, it probably won't be as useful as for some other types of photography.

Very good 77mm blue streak filter. The blue steaks can be rotated 360 degrees, which means you can point the light spots in any direction you want to create some very interesting effects. The images I've added are an example and were taken in the same spot I just rotated the filter to show how it works. So far I haven't had any issues with removing the lens filter that you can get with a rotating filter. I'll admit I didn't quite understand how this would work and tried using it during the day on a cloudy day and obviously didn't get anything, but I can confirm that this filter does the pictures I took has not affected, so you can put it on your lens and as long as there are no lights, everything is fine. For this to work you will need a light source, street lights, car headlights, wall lights, etc. BUT note that you cannot choose the light source. So if you have multiple lights you will get the flare effect on all the lights. I tried this on an 85mm lens and with the lens filter on I was still able to attach and detach the lens hood as normal. The filter doesn't have an overhang on the lens, but that probably depends on the lens you're using. Overall I am very happy with the Blue Streak Filter and would recommend it to anyone wanting this effect.

You need some good, sharp highlights, e.g. B. if you point it directly at a bright light to get the most out of it. When you do that the effect is great and it's good at mimicking the blue streaks you get from anamorphic lenses. You can rotate it to any angle, which is handy for switching between portrait and landscape modes, but anything other than horizontal stripes looks odd to me. Probably just because we're used to seeing that in movies. Aside from the blue stripes, it's otherwise very clear and hardly detracts from the rest of the picture, which is great.

This worked perfectly to help me locate a hidden doorbell transformer above a finished basement ceiling. I needed to upgrade my transformer so I could use my ring doorbell.

A really nice product, works well for what it is. This doorbell is an excellent addition to our property. Very easy to use,

This doorbell chime is the third one we have bought and so far we love it. The indoor chime is super for our apartment which is hard to hear someone at the door from inside. So this is perfect! What we were surprised to find out when reviewing the videos, the chime bell that was plugged in inside the apartment also has a camera! It had a video of us plugging it into the outlet. Who knew?? So I guess if someone breaks in, the little chime will act as a camera and video the intruder. Wow! The quality is great, it was super easy to install, and so far we are thrilled with it. Just hoping it will continue working this well for the long haul. Great bargain for the price for sure.
