Selfsat HH-90 Motor for H10D / H10D2

I have no idea what the previous reviews are on about. This item arrived in three days from Germany, ok the instructions are in German. It has pictures! and you can download these in English if necessary. It fits and works perfectly with an h30d, all the holes line up and the modern antenna has a bridge mount which stops the motor from hitting the back. If not get a spacer! How can you put a review on a product you buy not knowing what it is?

Having bought one of these, I thought I might clarify the confusion caused by the other review. Unfortunately, it turned out to be unsuitable.It is a motor for a Selfsat flat satellite aerial. When used with a suitable receiver, equipped with USALS and DiSqC 1.2, it should rotate the aerial so it points at different satellites. Selfsat models H10D / H10D2 are mentioned, but some online investigation led me to think the motor would work with my Selfsat H30D. It doesn't. Although the mountings look similar, the spacing is wrong, so the motor is jammed against the back of the aerial and can't turn.The instructions were only in German, but I downloaded some in English. They were not quite compatible, showing different parts, etc. This product is probably not suitable for use in the UK.On the good side, it arrived quickly, was well packaged, and is sturdily built. With the right aerial, it might be an excellent product

Apparently it's a 'Satellite dish attachment', and is described as '1 x 1 x 1cm' This 1cm cube looks much larger - but by no means cubic - in the other views, and would appear to rotate. But what does it do? Why aren't suppliers forced to describe the function and the correct size of their products?
