Ive posted a few things about ebo-jager, some good some bad. im here to set the record straight as to what im saying. Sometimes it works and sometimes it doesnt. Ive had nothing but problems with it. Some days itll keep the perfect temp. others it varys by about 4 degrees. I think i may have a fective one but im not sure. Id still recommend it though. Id just be careful and make sure its returnable. Anybody else have similar problems?
