I'll start off with the pros: very good quality that I can see will last me a lifetime, and saves time when working on older bottom brackets.

Like the Park Tool double-sided headset wrench, however, this tool is an extreme uni-tasker that I only use because I feel like I need to use it after wasting my money. The pin spanner is only one size, which runs the risk of being useless if the bottom bracket needs a different size - a much better option is buying the Park Tool adjustable pin spanner, which fits every size. As for the other end, I give the same alternative to the headset wrench: a 12 - 15 inch adjustable wrench that has the added leverage to produce much more torque on extremely tight bottom bracket cups.

Again, if you work on bottom brackets frequently or simply have money to waste, then buy it. Otherwise get yourself a 12 -15 inch adjustable wrench and save yourself some money.

For removing crank assembly of certain bikes no other tool will do. It looks good and works well.

I was a little concern about being the right wrench for those vintage campi. work just like a campi tool that sells for double.

This spanner/crank tool worked great for me; no problems in getting the nuts off. However, it is a bicycle tool (very thin), which means it will slip off the nut when you apply pressure. So, I bought two over-sized washers and a rubber spacer, applied those against the spanner tool, secured the whole jig with a nut screwed on the crank, and the jig prevented the thin spanner tool from slipping off the nut no matter the pressure applied. In my case, once my jig was secured, the nut came off easily.

tool is about 2mm larger than the bottom bracket cup, but it works anyway if you use it carefully and with a spacer to hold it in place.
