5 out of 5 eggsWorked for Comcast

Pros: Easy setup works with Comcast Internet Plus.

Cons: None so far.

Other Thoughts: I set this up for my girlfriend and it worked right out of the box. No problems streaming Netflix, Pandora, ect.

She has the basic 25MBPS setup and works very well with that.

5 out of 5 eggsExcellent Value

Pros: Got this for free with a Buffalo WZR1750-DHP combo promotion, but even at regular price it is a value.
Easy Setup.
No hiccups in service yet after two months.

Cons: None -- except I can't seem to get over 30Mb/s on a 50Mb/s plan. However, since everybody else is pulling much faster speeds, I think it must be a setting that I am missing..

Other Thoughts: Unlike others, I was able to activate this on Comcast/XFinity using their website without calling.
I upgraded to my own modem/router combo because their Technicolor gateway wireless sucked. However, I was able to get 60Mb/s with their gateway wired and around 10Mb/s wireless. I'm only pulling 30Mb/s with this wired and wireless. Using the Buffalo Router with their gateway, I was able to get 60Mb/s wired and wireless. This thing is holding me back at 30Mb/s for some reason. I'm guessing it is just a setting, but I can't find anything.

4 out of 5 eggs

Pros: It's a d3 cable modem. It's cheap.

Cons: I had to reset once with power cycle. It runs hot as described by others. I just hacked an exhaust fan on top. Let's see how it runs.

5 out of 5 eggsWorks well

Pros: We have been using this modem with our Comcast internet connection for close to a year and have had no problems. Now that Comcast has switched to a faster standard, we will need to 1) buy a new modem or 2) continue at the current speed. Since the current speed is fine, we will probably not buy a new modem. But if we did, I would buy one of these with no hesitation.

Cons: N/A

5 out of 5 eggsSo far so good

Pros: cheap price. works with comcast getting about 60 m. running great for about a week hope it continues. Very Happy so far.

Cons: Comcast here wont let you self activate this modem but others you can, So you have to call them and get on line for a half hour with a guy that you cant understand what hes saying. But thats not the modems fault. Some peeps on here are saying they could but on the self activate page in my town it says cant activate.

5 out of 5 eggsPays off in 4 months

Pros: I was looking for a DOCSIS 3.0 modem to replace my old Motorola SB5101u DOCSIS 2.0 modem but did not want to pay $8 per month to Comcast to rent one. I purchased the ZyXEL BRG33503 when it was on sale and it will pay for itself after 4 months. Now I am able to take advantage of the Blast! internet service. Using the Motorola modem, my download speeds capped out at around 15mbps but after install the BRG33503, my speed jumped to 120mbps!

Cons: none so far

5 out of 5 eggsWorks great (finally)

Pros: It was only $29.99 when I purchased it here on Newegg, bought for someone that was renting a modem.

Works at true DOCSIS 3.0 speeds on Comcast.

Cons: Took two hours on phone to activate. (see other thoughts)

The power jack on the modem itself seems a tad flimsy, but not enough to take an egg off
