I breed pure and rare poultry and have been using Brinsea Octagon 20’s for nearly 20 years. I currently have 3 Octagon Eco and 2 Octagon Advance units and find them to be very reliable machines with good hatch rates. There is a great after sales service and If replacement parts are needed, they are quickly sent out from the factory. It’s also good to support a British company, especially in these politically uncertain times. The new models look really good too but having just given a friend my old Octagon Digital which was still in good working order after 18 years, I think my current machines will probably see me out!
