I've had this for a bit over three months now, and it has been absolutely awesome. It's more than just a dog dryer: it's also been fantastic for cleaning dust out of computers and stubborn corners, removing cobwebs from hard to reach corners, and cleaning debris from the depths of my truck. One of my concerns was also that I've heard many dog dryers need to be run on a 20 amp or above circuit: this dryer runs just fine on a 15 amp (to check, if you're in the US, a 15 amp circuit outlet will look like this: D= while a 20 amp will have one of the parts in the = be T-shaped.)As far as the dog drying capacity goes, imagine one of those hand dryers at an airport or higher end gas station. You know how they're forceful enough that they push out the loose skin on your hands and make it 'flap'? This thing blows air at a similar rate, something like 1.5 times the amount as those. My test subjects are a rough coat Saint Bernard, a Newfoundland, a Newf mix, and a German Shepherd mix.I can get a purebred, rough coat Saint Bernard or Newfoundland entirely dry from sopping wet in about 15-20 minutes. The water literally flies off their coat as you use it, and it is also pretty good for deshedding. Definitely use this outside if you have a high-shedding dog! My only complaint is that it's pretty loud, though my groomer friends say this model is quiet compared to other force dryers. If you have a sensitive dog, try putting cotton balls in their ears and/or a bandana flattening their ears to their heads. Two of my dogs are very shy, but have adjusted to it after a few uses. It's a bit louder than an average vacuum cleaner.Durability: I'm very happy with it. My dogs have accidentally knocked it off the side of my deck, off a counter onto a tile floor, and I've also accidentally sprayed it with a pressure washer. I've had no issues with it to date.Overall, I feel it was well worth the price I paid for it. I would buy it again.
