5 out of 5 eggsGreat Sturdy Switch with Built-in Power Supply

Pros: Built-in power supply with cloverleaf power cable and power switch on the back, so no cluttering and no fumbling over cables accidentally disconnecting the power.

Sturdy metal housing.
Sturdy metal housing.

Cons: Trendnet should continue to design small desktop switch with built-in power supply. All their newer models appear to use external AC adapters.

Other Thoughts: We have two of these running without problem for a couple years now. More expensive than the other version with AC adapter (TEG-S80G). But for office work I would always pay the extra for the quality. Also this is the only 8-port switch with built-in power supply that I am aware of.

5 out of 5 eggsDesktop Switch Perfection

Pros: - Very well built, feels nice and solid. The weight helps the switch stay in place.
- No AC adapter! This is such an awesome feature.
- Even with the internal power supply, the switch is only about half an inch wider than an average 8-port desktop switch.
- The version I received has a power switch located between the AC input and the first Ethernet port. Very handy!
- I personally like the black and green aesthetic.
- Performance is just as you would expect, fast! Handles multiple devices doing large transfers no problem. Has a full 16Gb backplane.
- No problems with jumbo frames.

Cons: - Indicator lights are hard to read unless looking straight at them. The light from the bottom LED bleeds into the top.
- The low power "green" switches like this one sometimes have link problems with certain (usually older) devices, but this is pretty uncommon.

Other Thoughts: This, to me at least, is the perfect desktop switch. Well built and heavy enough to stay in place. On-board power supply so there are no boxes to deal with under your desk. Size, while not tiny, isn't going to take up your entire desk. Indicator lights are useful and on the proper side of the switch (wires out the back, lights in the front). And it performs as well as can be expected. I've used various models of TRENDnet switches for years and have never had any trouble with them.

The switch I received has a power switch located between the AC input and the first Ethernet port. I'm not sure if this is an older or newer revision, but this was a very pleasant surprise. If this is a new addition, they should definitely add that to the feature list.

Also, the power cord used on this switch is a "C5" plug. This is commonly used on laptops and you can easily find replacements if you ever need one.

This is fantastic switch, but you can get a comparable 8-port switch for significantly less. I found the internal power supply and solid metal construction worth the extra money, but not everyone will. You can't go wrong with this switch, but you could go cheaper if the extra features aren't important to you.

5 out of 5 eggsSmall, simple, and effective

Pros: In case "gigabit for shoestring budgets" and "works right out of the box" don't suffice, there's no wall-wart AC adapter, so you don't have to worry about DC voltage, amperage, polarity, plug tip shape, or some beast of a box covering an adjacent outlet. Small, unobtrusive, quiet. Metal case provides some RF shielding (albeit unintentionally).

Cons: 10Base-T connections are "indicated" by displaying a lit connection LED but no corresponding traffic LED ("off" may mean "on"). Hard to distinguish green from yellow on traffic LEDs (gigabit v. fast ethernet, respectively). LEDs tend to light up adjacent indicator windows (a common failing on many LED panels).

If you lose the AC cable, you can't swap in a spare AC cord - the power recepticle uses round pins in a Venn-configured round sleeve, unlike the ubiquitous triple-slat within a trapezoid plug.

Other Thoughts: I have no way to tell if this is indeed "green" other than looking at the electric bill at the end of every month.

The only observation worth mention that isn't of the ordinary is that I can now "call" my boxes by hostname; previously I had to SSH, mount NFS shares, or browse to each computer's remote management URLs by dotted-quad. I don't understand why it works as networking is not my forte, but my machines work just fine now and that's good enough for me.

3 out of 5 eggs

Pros: Worked fine out of the box. Good value.

Cons: When I plugged in the NAS, the drive would spin-up and start clicking.
Even with no other ports being used, same problem. Tried all ports with NAS, same thing. Connected the Level One switch, works fine. Maybe a low power problem.

Other Thoughts: I saw another reviewer with the same problem.
Has anyone else had this problem and found a fix?
If so. let me know before I RMA it.

5 out of 5 eggsNice Piece of Hardware

Pros: Nice, sturdy switch at a great price.

Cons: none.

Other Thoughts: We are replacing our 10/100 switches throughout our (budget-concious, Parochial) school with these and I couldn't be happier. I have no diagnostic tools with which to test, but the network just seems to get smoother every time one of these gets plugged in, about 15 and counting.

5 out of 5 eggsExcellent Switch and why the negative reviews???

Pros: This is an excellent switch for the money. First off, I like it better than the TEG-S80G (I have one of these too). This version, the DB version doesn't have a wall wart. It has a real power cord and a real power switch on the back. I really like this setup. Less clutter on the power strip / UPS. Other than that difference, I think it's pretty much the same switch and this version is less $$. Go figure.

Now for the other silly reviews... first off, this is a switch, not a router and it wouldn't cause your NAS device to not work. For the most part, either it works or it doesn't. Switches don't care about protocol above the ethernet protocol. Sigh... And the review that said it tripped your breaker? Really? I guess you could get a bad power cord or something, but I find it hard to believe. If their was a short in the switch, it's hard to believe that it would draw enough current to trip your breaker. That would typically fry the insides first on the switch.

Cons: The only con is... is that you have to read the bad reviews. This version should totally out sale the D version IMHO. I like it better and as I said above, I have both versions. for $30 and free shipping??? It's a bargin... metal case, nice and sturdy... jumbo frame support etc.. it's nice.

1 out of 5 eggsNot worth it

Pros: easy to set up

Cons: This product absolutely does not work with Seagate external hard drives and NAS. I went from a great working system to a system that I could barely work with. The only reason I was going to change was to upgrade my speed. Customer service was also terrible to work with. After fighting with it for a week, I just decided to go back to my old system. I lost a weeks' worth of production time messing with this router. I wouldn't even give it a "one egg" rating.

5 out of 5 eggsGreat switch

Pros: Integrated power adapter

Cons: TRENDnet is not a big name

Other Thoughts: Previous gigabit network only through D-links DIR-655. NAS jumbo frame of 7936. PC jumbo frame of 9014. Max transfer was about 29MB/s. After putting the switch between the 2, max transfer has jumped up to 58 MB/s.
