I remember the adverts in the electronics magazines back in the day for the Sinclair scope and thinking, Sinclair making a scope it will probably be a pile of crap like all of the other Sinclair products. I had a Sinclair calculator, it was crap, quickly replaced by the Commodore SR-1800, I robbed the only useful thing out of it, the LED display. The two transistor radio kit never worked and a friend of mine bought a "Black Watch" which lasted a few days before it fell apart. Sinclair audio amplifiers, bought a few scrap ones, more crap that never worked. Amstrad had a bad name for some reason but at least their stuff worked. Sorry about the rant, but Sinclair products, that was scraping the bottom of the barrel.
