12-30V MAX 30A DC Motor Speed Control with Wireless Remote Controller Adjustable Switch Reversible Driver Governor Two Way Version + Limit Function

Using this to add a simple remote control feature to my garden railroad.

The speed controller is cheaply built. It is lightweight and appears to be fragile. It works just fine. It does everything it says it will do. The thing about this speed controller that surprised me is despite how cheaply built it is it is astonishingly tough. I do recommend this product to others.

Controller is garbage slow response from remote threw both items I purchased in the trash

Mine rattles a little bit in side the casing, but besides that.Its awesome.Be prepared, it doesn't come with batteries with the remote. It takes one 23a battery which is the small ones that are 12v.The remote with the antenna extended has some serious range!The reciever was in a basement and I was upstairs outside 50 some feet out in the drive way and it was still reliable.Fyi it doesn't have a memory of speed control when you unplug it from its power. So when plugging it back to a power source and you click to on position. Nothing will happen until you turn the speed up, which then it will remember your desired speed. Until you disconnect it from a power source again

Used to build a controller for my stern mounted trolling motor. Put inside a rather heavy duty waterproof box. Put the remote in a waterproof cell phone bag. Works like a charm! Shipping time was a couple weeks thus 1 star off.

This was my 3rd try to find a reliable DC motor controller. The other 2 were either to slow to respond -- or did not have a constant run "Latch Mode" .This controller even has a "bonus feature" -- variable speed control!The case is a VERY pliable thin aluminum perforated sheet -- you may need to protect it from other objects/machinery. A good product.
