Brinseas aren't worth the money in the long run (in my opinion).. I have bought a bunch of their incubators and other products.
I have had defective bators, turners, candlers and brooders that had problems when they arrived from
Brinsea as well as bators and turners that die after a few months of use
their customer service is lacking .. even when a product is "under warranty" they still wanted to charge me for replacement parts!
A few things I have experienced as well as seen many other people experience (and there are many threads on the subject):
The fans in the bator can cause issues simply because they are blowing directly on the eggs instead of circulating the air around the eggs... a 'fix" for that is to lay a towel over the hatching eggs to keep the direct air from drying out the membrane (and NO high humidity isn't a cure for it.. when the humidity at "lockdown" is hitting 90% and you still have shrink wrapped or sticky chicks even though the air cells and weight loss were perfect it's a bator issue.. not a humidity issue)
the brinseas can also suddenly change temps or fail to cool down and cook your eggs ..one of mine was spiking to well over 150ºF and still not shutting off (after using it for several hatches).. it now resides at the city dump
they can also do the opposite and suddenly fail to heat at all after a few weeks of "good" use
after buying so many products yeah.. i could expect to get a lemon.. but I got a whole lot more than just one.. which is unacceptable.. especially when expensive eggs are involved
if you only occasionally hatch and want a cheap bator then fine.. but if you plan to hatch a lot .. year round.. you would be better off with something that works much better and is much more reliable
and for the record.. i have been hatching out chicks for well over 50 years.. also sold a bunch of people on the Brinseas when I first got them because I was happy with the first bator I got.. but after a year of their products i wish I had spent all that money somewhere else since it went right down the drain... at least our local dump now has a lot of bright pretty yellow plastic to add some color to the rest of the trash
