My experiences with this unit have been nothing but favorable, beginning with the unit arriving three days early. The construction is very good including a stainless steel tank and corrosion resistant powder paint. The operating features include three level probe design, all connections are at the front of the unit, diagnostic test button and led's, drain and flush option (not available during purchase), input water magnetizer option (not available during purchase) excellent temperature control and accuracy and a long controller cable (16').However, checking and tightening all electrical and mechanical connections prior to installing the unit is a good idea. The tank assembly is not properly secured and may slide forward and back slightly, thus additionally clamping is suggested.Because scaling is a problem with all steam-bath generators, I activated the automatic drain feature and replaced the drain valve with a drain solenoid and added a magnetizer to the input water tubing. The unit automatically flushes seven times and empties the boiler at the end of each steam-bath session!However, the unit is not available with the auto flush/drain solenoid, so I purchased one from Amazon for $28 and wired it to J6 and set the DR switch (SW1) to ON. This is a good buy since other manufacturers sell the solenoid for $400! It actually does 3 to 4 flushes before draining.Chris
