Great disappointment. Weak fan resulting in non-existent air circulation. I wasted my money.

The worst thing ever.... it makes noise as if you have a vacuum cleaner on full blast!!! If you don't have headphones with noise cancellation, you won't be able to handle it. It produces very little heat for what it is, and overall the construction and packaging remind me of cheap Chinese products. It definitely shouldn't be worth more than 20 euros.
