Over the years I've used many brands of nose trimmers.
They all have been somewhat not good, even when you buy a familiar brand….
It takes at least 7-10 minutes per nostril to achieve somewhat good result.
and the battery is trash in every one I had.Can you recommend a really good "premium" nose trimmer in both being able to trim hair and battery?
I am actually willing to pay a high price!
I have a "Panasonic ER-GN30" that I got at a discount store, probably not more that $10-$15 US. It takes at most 30 seconds/side; I use it a couple of times per week and replace the battery every 3-4 months. It also works well on my ears.
Of course, everyone's hair is different, so…your mileage may vary, products may have settled in shipment, don't use if allergic to any ingredients, keep out of reach of children, etc.
