I have been diabetic for 20 years, but bought this for one of my dogs that was recently diagnosed, because the test strips are only $9 per 50 strips. Mine are $75!!! I compared it on myself with my Accu-Chek Aviva, and the Prime meter tested only 2 points lower. I ordered the control solution online, (There is a toll free # in your manual to order), to make sure it is working properly, and it is! Highly recommend you order the control solution to make sure your meter is working properly, and it is FREE! READ,READ, READ your manual FIRST, and there are numbers in your manual if you have any issues with the meter. Like other reviewers, the only downside is the placement of the slot for the test strips. It is located very low, and is awkward/hard to see, but tilting it up when you insert the test strip makes it easier. Highly recommend this meter and will probably use it for myself when my other one dies, as the test strips are so cheap! The Prime meter is great!
