This is the UV filter that serves as the base of the magnetic system. Once this is installed, other magnetic filters can be placed on top of it. No need to turn it on and off, just snap it on and off. Filter changes in 1 second. Makes the workflow much easier, especially if you are in a busy shooting environment. The UV filter is very secure and very, very thin. Thin is good, but also makes it difficult to keep part of the lens cap on. It's not a big deal, but it's worth keeping in mind.

I bought this equipment to replace an older system in my summer home. It is much better when it comes to seeing the main screen, which is illuminated much better than the old one. I like that all the sensors are in one station too. The old one had 3 different sensors. Sometimes one of them would not connect to the main station, but I am not having this problem with the Sainlogic system. The only downside is that the temperature outdoor sensor is not as accurate as I would like it to be. It appears to be too cold on the lower readings (at night) and too hot in the daytime readings. I realize that I can calibrate this feature, but have been reluctant to try because if I set the daytime reading to what my thermometer indicates then the night time reading will be further off. I will try and see what happens. Overall, I am very satisfied with the equipment and look forward to a long useful life.

I've always been curious about the air quality in our home and this device has been great! It's interesting to see what affects it in our normal lives such as cooking.

I decided on this 6 monitor one because of the PM readings. Having asthma I want to see how it affects my breathing if we have higher PM readings. I also will be very curious of the CO2 levels once winter hits and our house is mostly closed up and doesn't get much fresh air.

Definitely a very nice little gadget for those concerned about their wellbeing and what they're breathing in

The idea of a magnetic filter system is very good, in the set you get the mount, circular polarizer, UV filter and an ND1000 filter all inside a nice quality pouch to keep them safe. This set is ideal for the landscape photographers out there, the ND filter allows you to slow down the shutter speed to enhance the effect of movement, the circular polarizer allows the control of reflections. Overall a very handy set that will be a permenant part of my kit.

I like the material and the display is pretty good. This is good to know about CO2 and the air quality at home. I would recommend it

Had been looking for a good system for my RV. I work out of state and live in my RV most of the time. I wanted something to capture weather details and have access when back home. The winds get wicked strong at the RV and I wanted a way to capture that, rain, and temperature through a couple of sensors (one put in the passthrough of the RV to warn of freezing Temps. This works perfect. The app leaves a little to be desired (third picture) but using the web interface through WeatherUndergroung or Weathercloud solves that issue (WU web pics after the app pic). Large display is easy to see and very customizable. I may get another for my home also!

We ordered the camera for our home and less as a surveillance system and more to see what our dog is doing at home while we are away from home for an extended period of time. The camera is very easy to install and works flawlessly via mobile phone, making it easy to connect to check how the house looks. Due to its size and appearance it is not very conspicuous and very nicely made. We have it on a shelf where you only notice it if you take a closer look. It picks up even the smallest movements and signals them to the phone. It can also record videos. It should also be mentioned that the quality of the image is also very good and images can be seen even in the dark. Personal highlight is the solar panel,

I originally bought this UV filter for my Air 2S drone to protect the camera lens from dust and dirt caused by flying the drone. The drone itself comes with just a rim frame with no lens for the camera. Right off the bat, this item feels well made. In that sense, I'm new to camera drones and filters. Just buckle up and do what it says. I live by a lake and fly over it all the time. This is from the other night with a longer exposure. Works as advertised.
