This unit replaced a Steamist SM-5 that I had for 14 years.Pros:1. Price - Less then 1/2 the price of replacing just the control unit alone on the Steamist, which I did. This unit only has to last a little more than one year to give me the same return on my money as my Steamist did, which averaged $142 per year.2. Relentless build to the target temp. Almost never drops in temp until it reaches the target and then stays within a degree or so of the target. This is not true of the Steamist which drops by several degrees several times in a steam session.3. The steam is only off for a couple seconds to generate a new batch. The Steamist would take a few minutes.4. The steam seems much safer than the Steamist which I constantly had to keep moving my feet away from as it got hotter. This unit just as a small triangle (with 1' - 1.5' sides) where it is too hot to place your feet. With care, I can stand and place my head above the steam for as long as I want, it seems..Cons:1. Celsius only - The mfg verified there's no way to display in Fahrenheit2. The steam cloud is 1/8 to 1/4 as thick as the Steamist which, at it thickest, I often couldn't see the control light on the wall. I've already gotten used to the thinner cloud this unit generates because of the pros given above.3. The steam only lasts for a minute or less before new steam must be generated. The Steamist would last 5 to 10 minutes with each steam batch but would take several minutes to generate a new batch. I've gotten used to short blasts of steam because of the unit's relentless build to the target.4. My steam room is 110 cubic feet and I personally wouldn't buy this unit for a larger room.5. The manual recommends that the control be installed outside the steam room (even though the title says its waterproof) which was almost a deal breaker for me. I installed it inside my steam room inside a waterproof plastic box. I've come to see this as a positive as it will greatly speed future installations.
