    Good to Great, but not perfect as yet!
    [This review was collected as part of a promotion.] I bought this during a sale period based off multiple positive google and product reviews online. It has been very easy to use but one slight reason lowering the review from 5 stars is the automated modes where you can plan delayed on or set off time. It seems that you can only do one or the other and not both settings...I'm hoping to do a bit more research but the instructions and function are unclear. Otherwise the product itself has been excellent and I have used it in my toddler's room without any issues.

    Awesome Heater
    [This review was collected as part of a promotion.] Brought this a month ago. Have been so happy with this heater the warmth and heat it gives off is so comforting and makes you feel all snuggly. We have a large open plan home and this heater warms it up so fast it's amazing.Cold home is behind us now our home is warm and inviting now when we get home from work as we have the timer set to warm up 30minutes before we walk into a lovely warm home. 7year warranty nobody else has this which made our dicision easier also.
