My new generator arrived in a few days. The generator was well packed and appears very sturdy. It took my plumber about 2 hours to install so I'm assuming it was relatively easy. I absolutely love it. Never thought I could add steam to my shower but so glad I did.

Delivery took longer than expected but the steam generator is top notch. Works great and produces a lot of steam. I got the iButler package which has dual controls for temp and wife likes to stay in longer. Anyway outside of the delivery timeframe I give the generator 5 stars.

Just had the MS400 installed by my plumber. My shower is a 4x4 and it puts out plenty of steam. Very pleased!
