This is a quality , accurate testing kit for anyone who wishes to test their blood/glucose levels, at a really competitive cost. ( i purchased the upgraded model with voice command for a couple of extra £'s - well worth it).Very easy to use and appears to be very accurate. Instructions are really easy to follow and i was ready to do a test with a couple of minutes of receiving the item using step by step instruction. What i also like about the product is that it is painless - anyone with a phobia of needles needn't worry as it is painless - you can hardly feel anything at all. There is an adjustable needle depth from 0 - 9, so try on 0 and just keep turning up to suit. Very happy with the product.
