After being a satisfied owner of the i-Stubble+ for 4.5 years, the head broke, meaning I was in the market for a new stubble trimmer. Some research later, I decided to go with the shiny and upgraded, Super Stubble XTP. After a few months of use, I can say that it is everything that made its predecessor great and then some! It has a solid construction - that of which you would have come to expect of BaByliss - and a much improved design (I particularly love the battery timer display which shows how much time is remaining until the next recharge). It also feels somewhat lighter in comparison meaning that it is easier to hold for long periods without annoying wrist ache! The ability to now shave in the shower is an added bonus alongside being able to successfully clean the head in water (finally!).
The shaving experience is the same, perhaps better than the i-Stubble+. I've had no trouble trimming on lengths between 0.4-0.8mm. In my experience, it is (and has always been) a little awkward to learn how to use BaByliss trimmers the first few times as you need to figure out which directions you need to hold it in order to cut the hairs. After a few uses however, you get the hang of it!
In sum, I'm extremely pleased with my purchase and highly recommend to anyone searching for a solid all-round waterproof trimmer.
