I love my Brinsea 20. I couldn't afford the Turner and didn't want the water tank. If the egg is fertile it will hatch in the Brinsea. I rarely do large batches so I use the Brinsea. I used lgs for several years and they are as nightmare. I bought a Hovobator which is as little better but it's still s styrofoam Bator and as pain to use. I sold the lgs and keep the Hovobator for a hatcher. I'm using an GQF cabinet for the first time this weekend.
