Warranty-breaking tricks to increase your epilator's lifespan

• Upon obtaining an epilator, figure out how to open it up and see the insides. The epilator may not be designed with this in mind. Screwdrivers, pliers, files, and other such tools may be necessary. Before each use, open up the epilator, brush out any hair inside, and close it.
• If a tweezer becomes stuck in the extended position, preventing the disc from rotating, the tweezer can be removed while keeping the other tweezers in place.

At the start of 2020, I bought an epilator. I did not follow these tips, and the epilator gradually became slower and more unreliable until it completely stopped working 32 months after purchase. Having nothing to lose, I opened it up and found a buildup of hair had irreperably gummed the gears.
With this in mind, I purchased another, identical, epilator, and followed the first tip. Speed and reliability were maintained, until 32 months after puchase, when a tweezer became stuck in the extended position, necessitating the creation of the second tip. Following both tips, the second epilator is still functional 44 months after purchase.

My friend suggests the epilators are only tested for 32 months' expected usage, and I suggest the epilator companies work on making epilators that actually last a long time.
