The trimmer features self-sharpening blades. The ultra-sharp blades remain sharp up to its(the trimmer) lifetime and trim without pulling or tugging hairs.

Cordless/Corded Trimmer

A cordless shaver/trimmer is best for traveling, and you can carry it with you anywhere for universal use.

But when you realize the battery is fully discharged and you don’t have enough time to charge it, but you have to trim your beard, then what will you do?

This Braun beard trimmer 3240 is both for corded and cordless use.

Don’t worry if the battery is fully discharged/dead.

Because it is able to provide you service while it is charging.

Even the charger is for universal use, you can use it anywhere from any country because it can adapt 100 – 240 volts.

Battery Life

This Braun beard trimmer BT3240 is powered by 2AA rechargeable battery. These batteries will deliver up to 80 minutes of running time per hour of charge.

The older version Braun BT3040 provided 60 minutes of cordless performance with an 8-hour charge.

That is why I like most the new version.

This shaver is designed with an LED display to give you the battery status. When you connect the shaver to the electrical outlet, the LED display will show the shaver is charging.

After fully charged, the battery LED indicator will be turned off.

After completely charging the battery, immediately disconnect it from the electrical outlet.

Removing the battery is so easy. You will get complete instructions in the user manual.

LED Indicator

60 Days Free Trial

After use, if you are not fully satisfied with this shaver’s performance, you can return it. But you have to return it within 60 days.

I think 60 days is really very long-time period for a trial, and it’s a great opportunity for the consumers.

NOTE: This service does not cover if your product gets damaged by an accident or unreasonable use.

Built Quality

The Braun BT 3040 is a very lightweight trimmer- only 11 ounces. So you won’t feel any pain if you need to hold the trimmer for a long time.

This Braun trimmer is engineered with ultra-sharp blades, and this sharpness will remain up to the blade’s life.

This blade is sharp enough to provide you with a precise trim.

But if you have a curly and thick beard, it may sometimes pull your hair.

There are 2 attachment combs with this package.

These combs will provide 39 length settings for beard and hair trimming.

There is a zoom wheel selector for changing the length settings.

 The trimmer feels very sturdy, but the attachment combs are not made with high-quality plastic. It feels fragile.

#Beard Trimming or Hair Clipping

You cannot find any shaver/trimmer Brand that can make a product perfectly.

But of course, some have been making the top and highest quality products.

This Braun beard trimmer 3240 is made with high-quality blades.

I think it will able to provide satisfactory performance, but the attachment combs are not well made.

They feel fragile, and they can break down with a little pressure.

So, of course, you have to handle it carefully.

Otherwise, the performance of this trimmer is able to obtain my satisfaction.

Whatever, I tried to provide all the features of this product.

Now, if you want, you can buy it and test it.

The great service I think of in this product is the 60 days satisfactory free trial.

So, you can return it to the dealer within 60 days after trying the product if you do not find it satisfactory.
