2 out of 5 eggsNot the best bang for your buck

Pros: Low cost per Gb
Managed access
DB9 console port

Cons: Unreliable
Prone to firmware problems
Prone to flash memory corruption
Does not handle actual enterprise environments well

Other Thoughts: This switch, at first glance, is a great value. One of the lowest cost per Gb switches you can find with this density. However, after having the misfortune of managing a dozen or so of these switches over the past year, I've found that the downtime and general problems that plague them is not worth the price difference between this and a more proven brand of switch.
My problems have ranged from the management interface not responding (a reboot sometimes fixed this), to the flash memory becoming corrupted (web management would come up with javascript errors, single/multiple/all ports would lose their configs, the switch would go amber and lose its full config), to repeated fan failure notices when the fans were working fine (I still have not found a firmware version that fixes this), to simply having buffered logging crash the switch.
The GSM series is not built for the rigors of a 24/7 enterprise environment, and the "lifetime warranty" involves you going through 20 e-mails of Netgear telling you that your network's at fault, even if you replace the switch with the same exact model and it doesn't exhibit the same problems. Be prepared to spend days just getting an RMA.
If you are not a business with a decent amount of nodes (500+), this may work for you. However, the risk of downtime and headaches with Netgear is far, far greater than the industry leaders. Yeah, the cost of a full gigabit switch from one of the big boys may be double or more than this - but you're paying for reliability, and the privilege of not having to explain that it's not your network at fault.

5 out of 5 eggsGreat switch

Pros: Great performing switch
Great Price
Full featured

Cons: None
UI could be nicer...

Netgear support isn't really helpful, they're nice, but not that helpful.

Other Thoughts: I also had the issue of this thing losing my settings on reboot.
I called Netgear, was transferred to 3 different techs, during my long hold times I was messing around and fixed it myself.
Here's what you do:
Set all your configs to what you want and apply them
THIS IS IMPORTANT:
You then have to click the Maintenance Tab
And there's a link on the left that says "Save Configuration"
"Saving all applied changes will cause all changes to
configuration panels that were applied, but not saved,
to be saved, thus retaining their new values across a
system reboot."
There's a checkbox next to this check it and click apply and you're done.

5 out of 5 eggsNice Giga switch

Pros: I am by no means a pro when it comes to switches. This switch has worked great from day one. No issues or problems with the installed.

Cons: None yet

Other Thoughts: The free PS3 increased the value and made for a lot of fun.

4 out of 5 eggsBlue or Purple

Pros: A feature rich Gig E switch. Easy to use webinterface. Price. Color makes it stand out in my rack.

Cons: Will not remember any user customizations after unplugging the switch.(See Below) The fans make this a noisy switch.

Other Thoughts: For the price and the features it is a good deal. Now that they have the free PS3 it is even more worth it. I had a copier that freaked out and messed up the arp table. Could not find a way to clear it in the user interface had to unplug and replug. Lesson learned use the backup feature.

4 out of 5 eggslittle blue beast

Pros: Cheap 48 port managed gigabit switch.

Cons: SSH (SSL?) doesn't work -- based on fressh -- and simply causes a crash. Plus, configuring ssh/ssl is completely undocumented. Earlier firmware revisions lacked the ability to clear the mac tables thus require a reboot after any topology altering configurations (like creating port groups, vlans, etc.) NTP "broadcast" mode doesn't work at all. Unicast mode barely works. Firmware upgrades *always* erase the configuration -- not once has one kept any part of it's previous configuration.

Other Thoughts: As long as you leave it alone after initial configuration, the things are solid as a brick. I've had several in production for >2 years. It definately has it's quirks, but it gets the job done cheaply at the cost of some initial frustrations.
