Product review (3 stars): Unecessary parts
The Honeywell Humidifier includes a transformer, saddle valve and humidistat. The Installation Kit comes with the flexible duct,  duct starter, duct tape, saddle valve, tubing, wire, sail switch, humidistat and two 24 VAC transformers. Now I have two extra transformers, humidistat and saddle valve. The Humidifier doesn't describe what's included, so you don't know for sure what else is needed. This is very poor or deceptive practice by the manufacturer. Amazon could also do a better job listing exactly what's in the box so you know if any extra parts are needed, and sell them separately. I ended up paying for a lot of extra parts I don't need. The few parts I did use in the kit I could have bought at the hardware store for about $20. Honeywell products are usually top of the line but in this case they pulled a fast one on the customer.
