They are fantastic, mines on 24/7 without a problem.. I bought a clearview 500, though expensive to start with the heatings hardly on anymore.. I would not bother unless you can get cheap or free wood, though a ton bag costs £50 up this neck of the woods and lasts a while.. I have carpet with a rug infront just incase a log falls out etc when I open the door, though it hasn't ever before it's better safe than sorry
