I only needed a replacement beard trimmer (no need for a shaver as such) and was originally somewhat skeptical about the concept of using a small electric shaver with an adjustable trimming accessory. But the reviews were good, and I decided to give it a try.It turned out to be a great 3-in-1 appliance. PROs:1. The trimming accessory is simple, sturdy, doesn't bend arbitrarily, ensures uniform trimming length, and is easy to adjust. Do NOT pay attention to reviews where some people complained about incorrect trimming length. We should all understand that these scales are approximate and relative. What used to be 2.5mm on my old trimmer is 3.5mm on this one (2.5 produces something close to the 5 O'clock stubble). Just find the correct position. It's quite predictable from there. In my case, if I need to trim it a little longer, I just switch to 4 or 4.5mm.2. The whole thing is very easy to clean. The trimming accessory can be instantaneously removed (or put back on) and washed separately. To clean the shaver, just turn it on and wash it for 15 seconds under the tap, as recommended in the manual.3. It's VERY compact compared to a regular rechargeable trimmer but works no less efficiently. A significant plus for traveling.4. An unexpected but welcome advantage: a much smaller "contamination" area. With all my previous dedicated trimmers, small, trimmed pieces of hair were flying in all directions within the 2+ ft radius, and I had to carefully clean both the sink and the shelves around it after each trimming. With this one, the "contamination radius" is much smaller, and cleaning afterwards is so much easier...5. After a month, the battery shows no signs of depletion. Looks like I can take it with me on a month-long trip without any need for recharging it.CONs: None are too bad, but you need to take it into account.1. The shaver uses a custom 15V power adapter with a weird custom cable, and you will have to take it with you anywhere you go. Moreover, you will not be able to charge the shaver if you accidentally lose this power adapter, or it breaks. WHY, oh WHY can't they design these rechargeable appliances to use the worldwide standard, i.e. an USB-C port??? Any USB-C power source for notebooks and smartphones automatically adjusts to anything between 5V and 20V. It IS important to take as few cables/chargers as possible when you travel, let alone the risks of losing this stupid custom power adapter...2. Another universal design flaw inherent in 95% of all rechargeable appliances: Neither a small, recessed BATTERY OFF switch accessible only with a staple/small pin, nor a safety latch preventing accidental powering on. This IS important when you travel and want to put the shaver or trimmer in your luggage. Imagine something moving and pressing against the Power ON button during numerous bag loading/unloading procedures! It beats me why nobody thinks of this simple precaution when designing appliances that are frequently used while traveling...
