*by M***W on 15 March 2025*

I was really dumb and thought I had ordered the kit that came with the digital controller, so I was a bit sad and disappointed with myself. Still though, the product is good. I have no complaints with the quality of performance at all. Juts be careful you click the right thing and double check it at checkout.. I thought I had selected the right one but I must have stuffed something up along the way & didn't notice until it arrived
