★★★★★

I drink a protein shake every morning and was tired of washing a shaker bottle every day. I add milk and powder, press the button and leave it while I get ready. When I come back it's smooth, with no clumps at the bottom. It does better if you add the powder slowly rather than all at once.

I use it at my desk for instant coffee and matcha. The matcha used to clump no matter what I did, now it's nice and even. I've been using it daily for about a month and just rinse and dry it after work. The handle is comfortable and 380 ml is a good size.

Have a Question? See Our FAQs

How is ThermoSwirl different from a regular mug?

A regular mug needs a spoon, and powders often clump or settle at the bottom. ThermoSwirl has a magnetic stirrer built into the base that mixes your drink automatically at the press of a button, so coffee, cocoa, matcha and protein shakes come out smooth every time.

How do I use it?

Pour your liquid into the cup, add your drink powder or ingredients and press the switch. ThermoSwirl starts stirring automatically. Press the switch again when your drink is mixed and enjoy it straight from the same cup.

How do I clean it?

Clean the cup after every use and dry it thoroughly before storing it in a cool, dry place. ThermoSwirl is not suitable for the freezer, and it should be kept away from open flames and very hot surfaces such as stovetops.

How can I track my order?

When your order ships, you will receive an email confirmation including a shipment tracking number and a website link where you can monitor your shipment's status.

When will my order ship?

All orders are shipped within 48 hours of order confirmation. You will receive an email with your tracking number once your order has been shipped.

How long does delivery take?

Standard shipping takes 5-12 working days depending on your location. We work with reliable shipping partners to ensure your order arrives safely and securely. Delivery times may vary slightly during peak seasons or due to weather conditions.

What is your return policy?

We offer a 30-day return policy. If you are not satisfied with your purchase, you can return it within 30 days from the receipt date of your order.
