I've been using a variety of trimmers over the last few years, including a couple from some of the best known brand names in the world. I tried the Litmus trimmer after a recommendation, and this is definitely the best of all the previous trimmers I've used. Not only is it a fantastic looking product with great aesthetics and finish, the quality of trimming is phenomenal. It is also very very easy to use with inbuilt length adjustment and a digital display to see key details. The battery life has also left me very impressed - compared to the previous ones I've been using this one gives me almost 5x the usage for the similar charge. And of course, the price makes it a great value..
Overall, highly recommended - go for it if you're looking for a trimmer with good features, long battery life, ease of use - all without burning a hole in your pocket!
