Shang 32fxo channelbank: interesting

hye,

this enterprise seems to provide low-cost channelbanks, so it could be interesting.

Now, the enterprise is chinese and they posted here around a few times end of 2007 to promote their solutions.

I would like to know whether anyone has used these and how their experience was.

thanks for any help
