Query: Nice, but....

it only worked for about a month than started losing signal, beeping, display goes wacky. Replaced the batteries, reset the probes, did all the things you are supposed to do, but it kept going berserk. Returned to OSI for a replacement and the same thing happens. Can't recommend until they fix the problem. Suspect it is some cheap memory or poor circuits. Either way it is a BIG problem.It does look good however, and when it works, it was great.
