Anyone used this inkjet print-head unclogger

from http://cgi.ebay.com/NEW-Print-head-CLEANING-Canon-QY6-0049-IP4000-I865/220517985334

?(question mark not part of the address)

It comes with the tools to do the job, using a fluid, the kit costing $14.95 + $7.95 p & p.

We have two Canon i865 printers, same age (four years), same problem: clogged print heads. Cost to get fixed here in NZ: NZ$245 ? each! I’d replace the things myself, but haven’t been able to find a seller of print heads here, yet.
