Question: After a few wks of use the orange grid is getting dark from the heat. Did anybody have the same issue?
Document: I love my heater and love all the features of it and the cute design is an added bonus. Unfortunately my daughter's room is the coldest room in the whole house, so we needed something small, but something that would even out the temperature. This was a great choice! The only negative is that after 2 months of use the orange grid is getting dark in the center from the heat, which makes it look dirty.
I use this heater in an RV. Works great. I have it next to a doorway and use the rotating feature to put heat into both rooms. I have used it for about 4 months now and have noticed two 2"x2" dark spots appearing on the orange output grid. It looks like the output grid is dirty but I think it is actually a discoloration of the orange area due to the heat. If you can't handle the grid looking dirty, this isn't the heater for you.
Small but powerful, this unit gets a 15 x 15 foot room warm in about 20 minutes. It's so quiet I keep putting my hand in front of it to see if it's on. The oscillating feature is quite too! The unit itself could use some design changes, what with the orange grate and all the warning signs so large and stuck all around it, but for the money it's worth putting up with the funny looking thing. I think it was a great purchase.
Heats up a closed room in minutes. No room size is too large for this fire breathing furnace. I've had this heater for 2 years now and it hasn't failed me yet. The orange plastic face is still intact, and it still works as if it was brand new. I practically use this heater everyday in the winter, and sometimes in the summer for it's fan function. My family also loves it so much we're considering to buy another one.
I bought this compact heater for its looks (the orange accent) and small size. I was a little worried that it was insufficient for my intended use - heating a rather large, vaulted ceiling sunroom. It has worked surprisingly well. I did not give it five stars because I think it is a little overpriced, and it lacks a thermostat (often called freeze protection). I have another bulkier heater that I paid less for that does have those features.
High setting is ample enough to heat up a regular size bedroom in reasonable amount of time.Cons:- none for me really ... coloring is kind of weird? The orange doesnt match anything in our nursery :)
Summarizing some of what I read before purchasing, the pros are great: very compact, very quiet, pretty amazing how it can heat a small room like it does. The cons are that it still has a bit of a smell to it (less over time--I hope it isn't bad for anyone's health! ).I don't know if this one was mentioned: all photos I've seen on it (including the packaging it comes in) make you think it is white and orange.
My office at work is freezing so I bought this to go under my desk. The oscillating feature helps it from getting too hot just blowing at one spot all the time.
We bought this for our infants room. Her room is 13x13 and it did an amazing job getting it warm and keeping it warm. Purchased a wall plug-in thermostat w it to help regulate the temp, works very well!
I put this in a corner of our master bathroom and it keeps the room nice and warm so you don't freeze getting out of the shower. During summers, my wife used to turn off the air conditioner when she took a shower and I'd angrily watch the house temperature rise. Now the house stays comfortable and so does my wife. Happy wife == Five Stars
