The main thing that has kept me loyal to Brinsea is that three-year unconditional guarantee. I can’t tell you that the machines have been error-free but their customer service has always taken care of me. I like having many incubators of different sizes so their line just works for me.
I doubt I'll get any kind of guarantee because I purchased it through an eBay auction but it "says" it was only used twice and they just purchased a larger incubator. Fingers crossed!
