Filzer is a Canadian marketing company offering MEC private labeling. Cheap tools as with other "cheap" items are often not the bargains they appear to be. They may work for an occasional user and certainly would live a short life if used in a professional setting. I always try to buy the best I can afford and most of my tools have given me 15 - 20 years or more of service life. That is worth a few dollars more to me. YMMV.
