First and foremost it's much less noisy than a regular dryer and it operates at a temperature that's safe for my dog.
It is super-easy to handle because it's light and has a comfortable grip due to its long rather than bulky design and silicone wrapping. That makes it the perfect travel item as well.
The different attachments are practical and I feel like I could use this dryer for myself too.
My dog tolerates it and doesn't get worked up like he would with a regular dryer.
