Does what it claims

Installed as per instructions. No issues. Works as it should

I was excited to find an ATS with three inputs instead of two, but the shortest switching delay (programmable) is 1 second. My original plan was to use this switch to connect devices that sensitive to power interruptions through this switch so that when the grid voltage dips, as it frequently does during storms, it would automatically switch to another source. Switching delay notwithstanding, this is a fantastic programmable switch.

it doesnt work.. period. no instructions but i found some online... but it literally doent do anything. Got a dude and i dont have the option to return for some reason.

The media could not be loaded. It's exactly what I was looking for. I always wanted one that worked with 3 inputs and was simple and didn't look intimidating. All the extra features and displays just blew me out ofbthe water. I have been recommending it to other van lifers all over the internet and promoting the product. Love it. Just wish had better documentation (honstly it may have came with one but I might have not paid attention and lost it) I wish I knew how the switch connection on the bottomg right works.

Despite re-tracing the PCB and replacing the SMD electronic elements the ATS looped and did not work. The first ATS bought from the so-called brand - Mastek works. The second issue ATS - DOESN'T WORK. See the pictures and the text above!!! I will think twice about buying this DECEPTIVELY compact and functional ATS...but poor quality. I feel cheated by the seller Mastek and by Amazon!!! Money back! I'm asking!? My wasted time waiting to receive a working product and the time for correspondence, WHO WILL PAY FOR ME!??? Will Mastek or Amazon pay the merchant!?

Small, but has 3 power sources and handles 60 amps. Also a greatred led display, volts on each line in, and total current out.

Mount this in a Circuit Breaker Distribution Box (likely need an 8 DIN) and you have a pretty cool RV autocrossover with voltage readout. Very functional, and programmable. I mounted mine right over my breaker panel in my trailer conversion. Nice to have any sources plugged in all the time, inverter, generator, and city, and it tells me what is on and selects the best one. What more could you ask for. Many RV's overcomplicate this for hundreds, tons of weight and no data readout.
