Summary: My old one was the same brand, but after a few years would not hold a charge for more then one cut. This one comes with a lithium battery, should last a lot longer. Plus the number box that tells you what number its on is bigger that you can see it now. Plus there are a total of 3 metal head that pop right off and on for just stubble ,goatee, or just a beard. Nice improvements and it was 10.00 less then the old one!
Summary: I had been using Remington MB300 (not in market any more) for several years until the adjustable guard lost a tooth recently. MB4040 is an improved version with some changes. The motor is more powerful and quieter and lithium battery stays charged at full power longer as claimed. I have had the trimmer for two weeks. I used it for trimming beard and hair with excellent results. The adjustable guard and attachable heads come on and off easily.
Summary: this is my second one, i did not have good luck with the first one at all. after about 4 months the batteries would not hold enough charge to complete a shave, then the head brok, no way to order a new head too. i really liked the feel and power it had when it did work good. but i waited 2 yrs now or so to order this one. wish me luck lol.
Summary: I don't know how many Beard timmers I have bought in the last 30 years buy this has got to be the best so far,it does a great job very even you don't have to keep going over over your beard for 15 0r 20 minutes to get it right this beard trimmer does the job and you can't beat the battery life.
Summary: It's nice and sharp, This is ALWAYS been a complaint of mine with other trimmers. Changing the blades could be a little tricky but after a few times of doing it becomes easier. A really nice feature is the depth setting for different lengths of trims. Long battery life is a plus.
