Small batch convenient, price not so convenient.

It may seem petty to fuss about a few bucks but considering what it is that is being purchased but its not like these branded heatshrink and ferrules are anyway shape or form superior to ones you may find at a ferrule supply site.

Overall I liked this set of ferrules and heat shrink. The value is really only there when locating proper gauge ferrules elsewhere is out of the picture.
There are better deals per ferrule/heat shrink out there than this.
bottom line though, is they help tidy up system connections and make it easier to remove and install components with set screw lugs without frazzling the wire end into a dreadlock. A+ for everything but cost.
