Title: It started to sounds like a motorcycle after 3 months of use.
Review: I've used that in a daily basis for 3 moths and now it is emitting a loud noise which prevents me from using it, since I've bought it to keep in my bedroom. It's impossible to sleep with that sound! I will contact the vendor in order to try to fix that noise or get my money back, but I don't recommend this product at all.
