Bought my existing UA-611 in October 2016 and it's been used on a fairly regular basis since then. It had never been re-calibrated so I bought a replacement - same model, therefore small, neat & easy to use. Pleasantly surprised, too, to find very little difference between new and (old) readings: 161 (163) : 80 (85} : 71 (73). So still almost as good as new even after over 9 years of use.

Very easy to use, very pleased with this item.

From ordering to delivery excellent service
Using the B/P machine was so easy so thank you

Very pleased with performance but felt if it recorded date and time in memory would have been handy!

Good prodcc
