1. Security start step
(1) Put the engine model in a horizontal position.

Wipe the piston and the outer wall of the spindle, confirm that there is no oil stain or foreign matter to ensure that the flywheel runs smoothly.

Works great and so much fun!
Color: Black
How did I live without this for so long? I love this little gadget! It gets used multiple times a day. It's not only great for frothing milk but it will whip eggs for a recipe and stir other ingredients as well. People who have complained that the stirring attachment was missing a piece did not read the description. The picture clearly shows there is no "boot" on that attachment, you don't want that one to spin like the frother. The Frother holds a charge for quite a while as well. I use mine multiple times a day and it is still holding a charge after weeks of daily use. Great item!

Disappointed

Powerful, but the description differs from the actual specifications, and the speed cannot be adjusted.

The perfect whipper for protein powders
Color: Blue
Love, love this whipper. Had to finally replace my old one that I got several years ago that was battery operated. This rechargeable replacement is incredible. Thought I would miss my old one, but no. The 3 interchangeable attachments make it my go to for a ton of things. Perfect for mixing protein powders!

Reliable favorite kitchen tool
Color: Blue
This wonderful tool may be the most used tool in our kitchen. The hardest thing about it is to remember you can push the button and it runs- you don't have to hold it!. The charge on the rechargable battery last a long time- about 1 recharge per month- and we use it daily. We use the mixer attachment most. It works great for protein powders, collagen, iced tea or lemonade mix. It cleans easily and is waterproof- just make sure the cover is over the charging port. We have used it to froth milk, whip eggs, and as I said we use it daily to mix beverages. I worried about the price, but it is a great value because we bought it in December 2024 and it is more powerful and has already lasted longer than two whimpy ones.
