First: Those Integy/Duratrax chargers are good. Fast, light, easy to use (dont have to choose between NiMh or NiCd or anything else) and reliable.
Second: Neither Integy nor Duratrax make them. They are made by Apex (
www.apexhk.com) However, some of the Integys have sligthly different software. The Apex and older Integy versions can be upgrade to this VESEC 2.5 software.
