This is the wall 3in1 personal trimmer and this is the manscape lawnmower 4.0 and today we are going to break down the differences between these two trimmers now first off we're going to have to adjust the build quality and ergonomics of these two trimmers because the wall easily beats the lawnmower 4.0 here first off when it comes to their weight the wall weighs in at 219 g whereas the manscape lawnmower 4.0 weighs in at 124 G and personally I just do think that there's something is very nice about the overall density of the wall but also there's just the ergonomics of these two trimmers now the lawnmower 4.0 it does have a lot of flat surfaces
