Rocyis 2-in-1 Electric Milk Frother and Coffee Grinder - Portable Cordless Rechargeable Drink Mixer for Latte, Cappuccino - Perfect for Camping, Traveling, Home and Office Use

Lasted a whole 5 times and now doesn't work. Tried contacting seller and no response.I was looking for a grinder and was surprised to come across a grinder / frother duo. I didn't realize I needed a frother but it helps to make a great latte. I like that the grinder will only turn on when the lid is closed. It seems to only grind enough coffee for one cup because when I tried to fill it it wouldn't run. There is a max fill line I didn't see. The lid is clear so you can see how finely it grinds down the beans. It comes charged and doesn't take up much space. I think it's a really cool idea to have both in one appliance.With this Portable frother and coffee grinder, you can have some fancy coffee with you pretty much everywhere. Picnics, camping, parties...this will be an essential tool. The other good thing about this product is that its rechargable, no need to buy batteries and power outlet. So far, I've only charged it once since I got it this summer and used it multiple times already. I only wish that the milk would have been warm or hot after, but that would take a toll on battery life if it was an available feature. With the material its made out of, it feels and looks very durable. I don't know about the motor part, it remains to be seen and I will update this review if needed. Its also easy to clean, and a simple rinse with warm water in the frother part with a little dish soap...run it for a couple seconds and rinse it again and you are all set!Overall, this is a good buy! I would recommend it for all coffee lovers like me.So, the milk frother portion works amazingly well. it's got a nice sized frothing cup and includes a little fill line so you don't make messes. it secures nicely and froths like a champ. The grinder portion also works really well.. I don't grind whole beans, but I do grind down normal sized grounds for use in moka pots, so I often run a coffee with a flavor I like through this thing. I do notice it sometimes gets caught under the blade, but they include a little scraper tool / brush to get that out. I like that the grind container has a locking mechanism to keep the lid from flying off, but the little gasket that forms the seal keeps popping out. I like the convenience of having a device that does more than one job, and this thing definitely does that. I just wish the build quality was slightly better. Now, that could just be the unit I got, but even then... still think this is worth a buy, just don't be super rough with it.I wanted one for the longest since I started drinking ice coffee! Works awesome!This portable milk frother/coffee grinder from Rocyis is seriously the coolest coffee gadget that I own! So not only does this grind beans and froth the milk, but its USB rechargeable! No batteries or power cords to deal with! The device is easy to clean and separate. For me, I really wanted a frother because the previous one I had was battery operated and made a huge mess. Because this has a cup included, I no longer have that issue of splashing milk everywhere! Super easy to use: just double click the power button to start and it automatically starts grinding and whipping! No need to hold down the button. This arrived with a bit of a charge so I was able to try it out immediately. I haven't needed to recharge yet, but it will likely be a breeze. Overall, I am super impressed and would definitely recommend this product to anyone who loves making coffee at home, particularly grinding the beans and adding some froth on top!
