just to point out this is a hydroponic t stat not a reptile. plants can stand the temp flux but so can balls 90-95 in dream temps. and yes very attainable but if a person cant afford to buy the big brands(helix herpstat ve) this is a very good cheap alternative. i been using a hydrofarm for 6 or 7 months and my temps do not have the massive temp gradient i set mine with an accurite temp reading to 93 and my temp flux between 89 and 95 some people this is to much but i haven't had an uti or any medical conditions since the switch from reostat to the hydrofarm. may not be good for some but for the less financially set people its good alt.
