Gamma Piu 025 Professional Cordless Clipper
This is my third electric trimmer. The first one was a cheap, cordless Chinese one I bought off Lazada; it worked for 1 month then the battery conked out just when the replacement warranty expired. The second one was a corded Philips one; it worked well and was relatively cheap, but the adjustable sliding (not detachable) guide comb didn't make for an even cut for shorter hair.
I eventually ended up buying this one because of the online reviews. It's made for salon professionals, so you can expect it to last long even with daily use. There are three detachable guide combs that you can use for any kind of cut (I trim my hair and beard every week). The battery lasts long between charges (around 3-4 full trims) with no sign of degradation, and it comes with a replacement battery as well. The clipper blade movement is quiet and fast, with no signs of jamming.
I'm very happy with this Gamma Piu trimmer - I don't need to get monthly haircuts anymore (which ends up paying for the premium price of the trimmer), and it's especially important with the ECQ!
