This little incubator has the features of a full blown sportsman, but at a much small size and price. You set the desired temp and humidity and it does the rest. The fan makes a bit of noise, but well worth the noise for excellent hatch rates. Will hold about 20-24 LF chicken eggs, or a good 30 bantam eggs. The R-COM's seem to be a great bargin for those not needing the capacity of a cabinet incubator. On a side note, the SURO-20 I bought came with a one year manufactures warranty.
