Pros and cons

According to our beard trimmer expert

With the comb attachment, you can set the shaving length very precisely.
You won't have to worry about the maintenance of the beard trimmer much thanks to the self-sharpening blades.
This beard trimmer isn't waterproof, so you can't rinse it under the faucet for a quick clean.
You can only use the beard trimmer cordlessly, so make sure that you charge it in time.

Description

With the Braun Series 3 BT3520, you can trim your beard to the desired length easily. Via the dial, you can adjust the length easily in 0.5mm intervals. In total, you can choose from 40 different length settings between 0.5 and 20mm. With the 2 adjustable comb attachments, you can trim your beard very precisely. You can set one comb between 0.5 and 10mm. For the other, you can choose a length between 10.5 and 20mm. The trimmer has self-sharpening blades. That way, they're always sharp and need little maintenance. With a fully-charged battery, the beard trimmer lasts 50 minutes.

Nice device with a handy wheel

Handy wheel

I found the wheel you can turn to get different settings a very handy idea, which is what convinced me to buy it. Testing it only reinforced this feeling. Although I do wonder how long this wheel will last; it feels a bit fragile. But for now, I'm very happy with this purchase!

Sharp, easy-to-adjust trimmer

Different positions for lengths
Easy to adjust
Sharp knives
Not waterproof

I'm very enthusiastic about this trimmer. The blades are sharp and the length is easy to adjust. The length adjustment wheel turns easily, and with the various attachments, trimming is quick and easy. The trimmer comes with a small brush for quick hair removal. The only downside is that the trimmer isn't waterproof, so it can't be used in the shower or under the tap for cleaning. During testing, I also noticed that the trimmer doesn't pull hairs and didn't irritate my skin. All in all, I'm very positive about this trimmer and would definitely recommend it.
