I really like the convenience of this magnetic filter system. You just have to thread onto the base ring and magnets do the rest.
Each of the filters themselves are slightly heavier than the bolt on K&F versions, probably because they have to make the filter ring out of a magnetic steel instead of aluminium. Whatever the reason, they feel a lot more premium than the regular K&F version.

I've had these lens filter kit for a few months now. Unfortunately, the magnetic base ring got warped probably from pressure on my bag. They replaced it without any hassle. I would suggest keeping the base ring in a non-bendable case which is what I will be doing from now on. I would definitely buy from this seller again!

The K&F Concept surveillance camera is super quick to set up with the app and needs the appropriate WLAN reception.
In addition, there are numerous tuning options in the app by changing the monitoring period, alarm method (recording only, recording and light and everything together with the alarm system) and the option of hiding certain areas so that the camera does not start.
The quality of the videos, even with night vision, is surprisingly good and you can also see the people, you don't have a pixel mush as you know it from various cameras at Tatort.
In addition, the app also reliably sends notifications when movements are detected.
The audio function also works perfectly, I personally would only have wished that the duration of the light could also be adjusted, as I felt the light duration of 0.5-1min was quite long in order to be able to save battery if necessary.
Nevertheless, the product was able to convince us completely.

Had this for a couple of weeks now and seems reasonably accurate.
The remote sensor is powered by 2 AAA batteries and the base station can be powered by either 3 AAA batteries or the USB cable supplied.
The instruction manual does go into quite a bit of detail, lucky for me as not had a weather station before.
I've not had an connection problems but the remote sensor and base station are only about 8m apart with the remote being on my balcony and the base in my lounge.

I think it is worth the money.

Recorded a semi running a red light and nearly running me over on my first day of usage.

I would recommend it.

Just be patient when figuring it out.

This weather station utilises radio wave signal reception to achieve it's information, the unit can be installed on a wall so it looks like a panel or placed on a suitable surface utilising the included stand, it also has the ability to connect up to three battery powered sensors for the temperature monitoring of different areas and these will apparently work up to 100m away from the base unit, the main unit can be powered both by Usb type c cable or battery power with a couple of caveats if utilising batteries.

Item arrives boxed in a branded box which contains the unit itself, Usb type c power cable and instruction booklet, note however if powering the unit by batteries a total of 5 X AAA batteries are required, 3 X AAA for the base unit and 2 X AAA for the sensor, these are not supplied.

The weather station is comprised of high quality and durable plastic, the main unit along with it's sensor appear well manufactured, though it should be noted that the included sensor is not waterproof if mounting externally.

The weather station features a large high resolution LCD screen, thus providing easily read information such as the time, date, weather forecast, indoor and outdoor temperature, moon phase, humidity and atmospheric pressure.

The weather station features an automatic light sensor that adjusts screen brightness on it's backlit screen, however you can also manually adjust this to a level you feel comfortable with, the base unit itself can be powered via Usb type c or batteries, however if batteries are utilised the screen will go to sleep after around 10 seconds requiring a quick tap to engage it again.

Due to utilising radio wave signal reception all information should be gained when first powering on the device, however there are manual options of setting the time etc if reception cannot be acquired, there is also included an alarm clock function if you should choose to utilise it, thus making this an all in one solution.

There is included a single (not waterproof) sensor for use either externally or in another room, one sensor is incorporated into the base unit itself, therefore initially there are two temperatures displayed on the unit IN/OUT. The unit supports up to three of these sensors, therefore could theoretically monitor the temperatures of an additional three locations, assuming they are within range of the base unit, the price and availability of additional sensors is however undetermined at time of review.

This is a quality product that comes highly recommended for domestic use, hopefully for the business users out there additional sensors are easy to come by and priced reasonably, this would make for a great product to monitor additional rooms or sections too.

I used it on a music video shoot last week and it's safe to say the clients loved it. Oh, and the red ring around the filter is a nice touch, making it look really elegant on my lens. I wish all my filters had it. 10/10

A good looking base unit with a clear easy to read screen, the base can be run off of batteries and in this mode the screen goes to sleep, backlight turns off but you can still see some details. To wake it you touch at the bottom of the screen. Powering it via USB C connector allows the screen backlight to stay on, it has three brightness levels. The clock is set via radio so should be accurate, it can be manually set if there are issues with receiving the signal. The moon phases are also shown along with an indication of the potential weather (I think this is deduced from pressure, temperature and humidity conditions). One sensor is supplied but it can support up to three, the sensor automatically synced with the base but this can be done manually if required. The remote also shows the temperature and humidity on its built in display. The base displays internal temperature where it is located and the temperature where ever the remote is mounted. The remote operated OK over 20 meters away from the base, note the remote is not waterproof so needs to be protected from rain etc.. There are a set of buttons on the top of the base that are used to set settings etc. including an alarm clock feature if you want to use it as your bedroom alarm clock/weather station. The kit seems to be well constructed out of decent quality plastics, including the remote, no batteries are supplied with the station so you will need 5 AAA batteries.
