Review on Letyet 17oz Tumbler Cup with Lid and Straw - Bluetooth Speaker Base with Detachable LED Light - Stainless Steel Vacuum Insulated Coffee Cup - Double-Layer Powder-Coated Travel Cup (Blue) by Gabriel Tomato

I like the idea of a toggle switch and a speaker, but it's not quite right. The mug feels heavy but the plating feels cheap. It's a really smooth finish, almost like glass, it's definitely slippery when wet. I wouldn't trust it to be dishwasher safe or even last long. Two different straws are fine, but don't make up for the glass. I'll probably leave them for other mugs. The speaker sounds bad, even at low volume it sounds like music is playing through the end of the tunnel. The playback time is only about 2-3 hours at maximum volume when fully charged. It could be a really good idea if they spend some time fine-tuning the product.
