You have already noticed, the sweaters often easy pilling. The causes are multiple (types and qualities of Contents employed, friction, static electricity, climate ...). When it comes to discount sweater, no regrets, throw and redeemed (not very green anyway) ... But when we paid a high price his clothing and we still like to wear it, that's the disappointment! With this shaver, it can prolong the life of his favorite sweater. My wife searched long in physical stores such products but except for a small razor 4-5 euros in a discount store whose life did not exceed a few uses, we found no commercially circuit "traditional". Strange ... It's on the web where this material is widely available as we found our happiness ... This shaver is almost as big as a small iron. It can connect to power or run on batteries. Its cutting width allows it to work on a larger area and thus more quickly. Moreover, the weight of the device seems to indicate that the engine should be of good quality (larger coil). We will see in time. However, of reliefs or neck shirts for example, it is not always practical. I think this great complete razor with another smaller may be appropriate. 1 star less because a lithium rechargeable battery would be a plus for this type of product because the cable is not very convenient to use.
