I am a breeder. I have used many incubators in my life now… I’ve been creative and made my DIY units… till my last one ran out , I decided to look around and find something cleaner ( when put together), something portable and affordable… I am not a USA resident ( so $=$$$) anyhow overall I am very happy with this unit… I already used it some kittens and I will not stress it enough to a must HAVE! I tell all my breeder friends-you need one at all costs ! It saves so many lives and helps babies… please do yourself a favour and get one… also lifeline pets were fast to ship it out and I got it within days! Hope this helps the person reading my review!
