This is a helpful little kit and if you want to spilt to two outlets, it's a necessary add-on! The included duct does not expand much, so don't expect it to run very far from the heater. A joiner as part of the kit would be very helpful!
I expected this to have longer hoses than the one which comes with the heater itself, however it's a couple of hoses exactly the same size. Overall decent quality, but if you are looking to actually use it to provide 2 inlets into your environment, you'll probably need to buy some dryer duct or similar to attach to the t piece which comes with this.
