I recently purchased a Flyp portable nebulizer. The first time I used it, it "leaked" all over my hand. I tried to contact Flyp per the seller and got no response. I started posting questions about their customer service and their product. Seller finally replace device, same issue. Flyp sent a new one as well. Customer service decided they'd better deal with me. Haven't used theirs as I've been out of town. Has anyone else had these issues?
