Price is inclusive of tax and shipping, and there's a 10-day money-back guarantee. (On the downside, Sinclair were often very slow to ship and often launched product and took payment before they had volume production.)

By contrast, the HP-65 cost £490 in July of the previous year. No contest at all in quality, accuracy, features, but Sinclair wins on price by an order of magnitude.

Well to be fair, the Sinclair Scientific Programmable should really be compared to the HP-25 which sold for £119 in Sept 1975. Even so, the HP-25 was 4 times the price of the Sinclair (and well worth the premium if you could afford it).

The only Sinclair product I ever owned was the Sinclair Wrist Calculator around late 1977. I assembled it from a kit and it did work but there were mechanical problems with the case design and battery life for the six mercury cells was very poor. I had wanted to get the Sinclair Watch when it came out but I ended up getting a very nice LCD watch shortly afterwards. Given all the polyester I wore back then and the fact that we had a cat, the Sinclair Watch wouldn't have lasted a week anyways
