Fitting Instructions
- Slide the rubber boot down and disassemble the throttle housing, remove the old throttle tube taking care not to damage the throttle cables.
- Carefully remove grip from the old throttle tube if required.
- Inspect the cables and housing for excess damage or wear, clean and lube them or replace if required.
- Clean the handlebar and inspect for damage where the old throttle tube has been spinning on the bar if a ridge is present replace the handlebars.
- Slide the new throttle tube on the handlebar and lube using a penetrating lubricant preferably Maxima MPPL (do not use grease as this attracts dirt and makes the throttle stick after a short period of time).
- Re-assemble the throttle cables and housing again using some penetrating lubricant.
- Tighten the throttle housing in the correct position on the handlebars.
- Adjust the cable to the required (free play amount) of your liking.
- Rotate the handlebars to their maximum position to check proper operation of the throttle and correct cable routing, some re-adjustment of the cable may be required.

- Twist the grip to the correct position and leave to dry.

Excellent customer service and good product.
Color: Black
Really like this frother a lot, with the attachments. Great price and works well. That being said, it suddenly stopped working after a few months, to my dismay. However, upon reaching out to the company, they replaced it very quickly. So I do recommend it!

Great frother, dumb charger
Color: Black
Works well. I got this to replace my battery powered milk frother from IKEA. I use it to make a protein shake every day. I just take a 16oz glass, fill it halfway with milk, add a scoop of protein powder, and mix it with the frother, using a combo of low and medium power, but realistically, low is all you need for that purpose. Been using it everyday for the past almost month since I got it, haven't had to recharge it and it's still working great.
The only reason I'm giving 4 stars instead of 5 is because the charger is micro USB. Not using USB-C in 2025 is honestly just insulting. Change that and you have a 5-star product.

10/10 – I’ve Already Bought Three!
Color: Black, Color: Black
I absolutely love this frother. It works in multiple ways and makes the perfect creamy blend every morning with my protein and collagen. It’s powerful, easy to use, and the charging stand is super convenient.
I loved it so much that I purchased one for myself, one for my mom, and one for my best friend’s mom.
What really impressed me was the customer service. Mine stopped working at full strength, and they walked me through troubleshooting. When that didn’t fix the issue, they immediately sent me a replacement. That level of support makes a huge difference.
Highly recommend — I’ll definitely be gifting more of these!

Stopped working in 4 months
Color: Black
It’s hard to find a whisker that has good reviews. I was hopeful with this one because I wanted multiple attachments and speeds. When I received it I was close to returning it because the attachments were hard to take off and very fragile. I should have returned it at that point because 4 months later Ive missed the return window. I did not use often and if I did it would have broken sooner. All of the sudden it stopped spinning. I recharged it overnight and it didn’t help. Of the three speeds, non work except the middle speed that spins at a wonky pace, and turns off randomly. It’s garbage.
