We like the narrow footprint and how simple it is to use. It also looks sleek. I'm not sure how much the water reservoir works because a few days after filling one halfway, the same amount of water was still there. Perhaps it's not dry enough where we are, but I was hoping it was more impactful than it seems to be. Also, we have a rug that has some uneven piling -- it's part of the design. One of the plastic pieces that holds one of the casters broke while gliding the heater over it. The design of the casters seems to be really flimsy (see image - we've tried to use heavy duty plastic glues to fix this but it hasn't worked) -- would be better if they were made of metal instead of plastic, particularly since the four wheels hold all the weight of the heater. Lastly, the side arms that pull out from the top do not pull out easily. They tend to stick and also seem like they'll break easily one day. I just got these about two months ago but already have had to ask for replacement parts (pending to see if they'll actually send any) or I may have to return it. Got the heater via Target, and thankfully they have a better return policy than costway directly.
