Review on 🥛 Nestpark Portable Drink Mixer and Milk Frother Wand: Compact Hand-Held Mini Mixer for Bulletproof Keto Coffee, Cordless and Battery Operated by Matt Louis

I use this blender for 2 cups of coffee a day and change AAA batteries every 2-3 weeks. Love it when it works, it's so handy with the wall mount. The downside is that it's been out of service intermittently for over a year (the engine sometimes starts, sometimes not), which is frustrating. I have to fiddle with it, tapping it against the edge of the sink or playing with the density of the build to coax it back up. I need it. Without the sporadic engine failure I would have given 5 stars! If there are any suggestions for keeping the motor assembly stable (like advice on whether I should clean it with alcohol or WD-40 I'd appreciate feedback).
