The main improvement to the 5 Series is the Lithium-Ion rechargeable battery. Completely recharge in just 1 hour for up to 100 minutes of trimming.

Otherwise, the trimmer is similar to the MGK 3245, offering the same 80 minutes of precision trimming on an 8-hour charge.

It's a powerful trimmer. I tested it on 3 months of head hair and 6 months of beard hair and it powered through without so much as a whimper. I understand that is not the intended use of these trimmers, but I wanted to give it a solid test. Side note: When the test was completed, my bathroom looked like I had just shaved clean 3 unruly Scottish Terriers. So many trimmers are cordless, and rechargeable, but they all have a flimsy plastic base/cradle and a plug that you have to physically plug into the trimmer before you set it into the aforementioned base. But this little gem, this Braun 10 in 1, has a legit charging base/cradle. A weighted base/cradle that plugs into the wall that all you do is set the trimmer into it, it beeps to let you know it's connected and charging, and away you go. No more fumbling around with two wet hands trying to marry the male end of the plug into the female end of the trimmer, then you have to fight the charge cable that almost always will not comply and allow the trimmer to rest in the basic cradle, and on and on. There are 2 adjustable guide combs that are used for trimming long beards and hair. The small one provides 3mm-10mm trimming lengths and the large one provides 11mm to 20mm trimming lengths. In addition, there are two fixed guide combs for trimming the stubble that provides 1mm and 2mm trimming lengths. The combs are made with good quality plastic to make them durable and last for the entire life of the trimmer. The Gillette Razor: This BT3240 offers even more battery power with up to 80 minutes of cordless trimming. This trimmer is 100% washable for easy cleaning.

To maintain a neat and well-groomed look, invest in a high-quality beard brush or comb. Regularly brushing or combing your stubble helps ensure an even distribution of hair, while also training the hairs to grow in the desired direction. This practice prevents any unruly patches and helps you achieve a more polished appearance. Lastly, protect your beard from harsh environmental factors. Shield it from extreme cold or excessive sun exposure by wearing a scarf or utilising beard balm with UV protection. Waterproofing: Grooming in the shower has a number of benefits – not only does it wash away any debris almost immediately, but it can also make it easier to cut unwanted hair. If you're not a fan of dry trimming, make sure your gadget is 100% up for an aquatic lifestyle before you buy.As you can see, each trimmer in the 5 Series offers the same power and basic features. They differ only in color and included attachments. Look no further if you're after a sleek-looking piece of kit that will lend your bathroom some style points. This all-in-one trimmer features a useful digital display that alerts you when you're low on battery and comes with an array of attachments that magnetically clip on (much to the delight of our panel). The Braun beard trimmer and hair clipper kit MGK7220 comes with a soft bag designed to make it easy to keep your attachments and shaving accessories in one place. Given that the ear and nose trimmer attachment, the beard and hair clippers attachment, the body groomer head, the detail trimmer attachment and the mini foil shaver are all supplied with the Braun 10-in-1 MGK7220, being able to store everything in one handy bag is useful. Note that you can also store the four combs, Gillette razor and smart plug charger - also supplied - in the bag to keep everything organised when they are not in use, too. This series of Braun multi-groom trimmers are also great for beards. They offer many of the same great features, like lifetime sharp blades, with even more versatility. Patience and perseverance are essential when growing and maintaining a long beard. Avoid the temptation to trim it too frequently and allow it to reach its full potential before making major adjustments.
