At full length this device is a little cumbersome and clunky but, it does the job okay. The water jets at the brush head are not equal in their water distribution. Some spray more water than others. All in all, it is not too bad.

I’m new to all the drone stuff and figured I would get a really big power brick thingy and it works great

This transfer switch is well constructed and very solid. The handle moves solidly between each of the positions so there is no guessing what source you're using. The terminals are wide enough for almost any gauge wire. Including those 2 padlocks, one to prevent the lever from being manipulated by unauthorized personnel and the other to prevent anyone from opening the box with the risk of electrocution that nobody wants. Very good

Had expected this would be 10 AWG wire as write up says "30A Y-Branch Cable," but it is not - in fact on closer inspection it is marked 4mm (which is generally more commonly known as 12 AWG wire rated for 20A). I didn't notice this originally, and it took me quite a long time to trace back why my system was underperforming to these cables.
