For those of you who have gone through a number of battery operated nasal hair trimmers and been disappointed on each occasion (me included) this one may just solve your problem.
Besides looking quite stylish it works very well and in around 1-2 minutes it will have done a good job of getting rid of all that unwanted nasal hair. Its angled design makes it easier to navigate your neb (and ears) and unlike other ones I have tried, this trimmer doesn't pull the hairs out (which can be quite painful) it simply clips them like a pair of scissors would.
It's easy to clean, just use the included small brush or rinse the end under the tap, and it comes with 2 eyebrow combs (one short, one long) which clip onto the trimmer to allow you to trim your eyebrows. These work quite well and do a decent job.
Also included is a plastic cover to protect the blades and an AA battery (which is always nice). One small problem i've experienced is that sometimes when you switch it on it doesnt start and you have to take the battery out and put it back in again. This isnt too big a nuisance and it only rarely needs doing.
The battery life itself is good - i'm still using the supplied battery after upwards of 20 uses.
In summary, this is probably the best battery operated trimmer available and you wont be disappointed if you buy it. I would recommend it if you can avoid Amazon's steep postage for this product (about £5) ;)
