Productbeschrijving
Het grootste voordeel van deze camera is de lens met 45 x optische zoom. Deze lens, gecombineerd met een krachtige illuminator, maakt 24/7 bewaking mogelijk zonder extra verlichting, zelfs over een gebied van enkele honderden meters. Dit maakt de camera ideaal voor bewakingssystemen waarbij identificatie van personen of voertuigen vereist is.
Dankzij de "Starlight"-technologie is de camera zelfs bij zeer weinig licht voldoende voor een helder kleurenbeeld. Het door de fabrikant opgegeven bereik van de illuminator is afhankelijk van de omgevingsomstandigheden (luchttransparantie, omgeving, muurkleur, zogenaamde "scènereflectie". Reflectie van de scène).

A fine replacement for my old Macbook
Style: Apple M5 Pro chip, Capacity: 24GB Unified Memory | 1TB SSD Storage, Color: Space Black, Set: Without AppleCare+
Marvelous!
I didn't realise it no longer had usb A ports, so I had to order new cables.
Very responsive.

Perfect for home use!
Style: 4.0ah Battery Included
I have been using this saw to cut down branches around the back of my yard and it has performed great! The battery is easy to charge and can last a couple of hours, depending on how heavy it’s used. The chains are very sharp and so far have not gotten dull for using it almost every weekend. The power on the saw feels strong and sturdy, which is what I was looking for, especially while cutting wood or other materials. Setting it up with easy and the instructions were very clear. This is a great chainsaw since it’s light weight but would only recommend for small jobs or home use. I would not use it for big projects or heavy duty cutting since it will probably not be able to handle it. The best thing about this it’s that it’s compatible with almost all of my Dewalt batteries, which keeps me from buying other types of batteries and I’m able to use the ones I already own!

Weak battery base on saw module.
Style: 4.0ah Battery Included
Probably would work for light duty. I used this thing less than 8 hours (less than a single day of work) and the saw broke at the base that it connects to the extension pole.
The motor on the saw itself seemed powerful enough. It got hung up in a branch and then broke on one side of the battery slide in (which was connected to the pole extension, as per the saw's design)
Probably buy a more durable one if you're really planning on doing some work with it. Bet it was made for city people.
