5 out of 5 eggsFLAWLESS

Pros: I noted DanW's comments. My C504 has worked flawlessly for several years. I have 3 computers and a printer connected to the 4 ports. The printer has a static address and the computers are variable. My DSL speed is the highest possible and no problems with connections at any time.

Cons: None.

Other Thoughts: I do guard against nearby lightening strikes and remove the phone line during bad rainstorms. In the past I have lost several modems because of line surge and induced voltage in the lines. An improvement to a modem would be a on-off switch for the phone line.... to be turned OFF during rainstorms.

1 out of 5 eggsNot worth the money

Pros: Easy install and setup

Cons: Used this to replace an older Trendnet ADSL Modem, howeverm it started loosing connection after a week, updated firmware, contacted support and nothing.
After a few months of dealing with this, I removed it (ate the cost) and installed a competitors product.

Other Thoughts: I have used Trendnet products for over 6 years and never had any issues like this.
Have since removed all Trendnet gear and replaced with Netgear / Cisco.
If you need stability, stay away from this product.
