Summary: It works and is cheap enough when it's on sale that if you figure out what it costs and divide it by its likely lifespan, it may still be worth it. This is not, however, a business class switch. This is for someone who wants a rackmount switch in their home.
Pros: Was reliable while it lasted. Install looked clean with internal PS.
Cons: Appears to have a lifespan of about 30 months base on reviews here. Mine lasted 31 months.
Summary: I have setup over 20 of these switches on various networks. No software setup as these are unmanaged. Well built. We did have one switch go out after 2.5 years; however, it was due to a power surge on an Access Point and caused the switch to malfunction. Port lights all got dim.
Summary: Had one that burnt out (powered on but was not functioning) in ~1 year, replaced it with another one same model. Fanless = quiet which I like. Inexpensive = easily replaced. I bought an extra one just to swap it out quickly for when the next one burns out.
Pros: Worked decently when it was alive, although not real fast through put.
Cons: Died after 2 years and 2 months. Looking at the other reviews, it seems to be a trend. Probably has an inferior MB in it as it powers up, but I assume the board has to process and translate the power down to what the circuit needs.
