I never used them because the fan tends to dry the collared eggs out which is NOT good . The regular hovabator is fine, holds alot if you don't have a zillion lizards laying , lol. They are well worth it for a fairly good price, for most small hobbyists, without getting large expensive models.
Best wishes with your uroplatus fimbraitus, I had uroplatus henkeli for almost 10 years, just lost me last one this spring :0(
