I bought this gadget, and was enthusiastic about the idea. The quality is not great, but ok. The neoprene sleeve case should be quite useful, but not with leaking lid. Unfortunately, this spoils the quality of the product and limit the application range of the thermal cup on a home. But honestly, a thermo cup is intended for traveling, not for stationary use at home. It would be nice if a new, tight lid could be delivered.
Therefore, only 2 stars. With tight lid, the cup would be really recommended and worth the price.
