Review (2/5): Lasts less than a year
So, this is the second shaver of these general kind (5-head) that I have ordered. First one, in September 2020, this one in October 2021. I am now convinced that they weren't designed to last longer than a year.
Biggest problem is cheap plastic connectors around the button that over time gives way and compromises waterproof seal. Once the moisture is able to penetrate, it corrodes the circuit board connectors thereby killing a shaver. I rested the battery 🔋 (good & charging), tested a motor (good).
The question you have to ask yourself is whether $20+ is OK for 11 months of usability.
