APC is a trusted brand - this guy is beautifully thought out!
Color: Black, Size: 8 Outlet, Style: Outlets Only
It's hard to get excited about a power strip- but when they designed this one, the engineers at APC hit it out of the park! I love how the 'wall warts' (those odd klunky AC/DC power adapters that so many devices come with nowadays) have their own spot on this unit, and do not block out the remaining plugs that regular AC power cords (3 prong grounded) require. This is VERY important! Most of the competition has you forfeiting one or more plug locations when a wall wart blocks you out! There are on/off status lights (green means OK) and and on/off SWITCH. For the modest and reasonable cost, you get great surge protection. I have used APC products for many years, particularly fond of their backup UPS power supplies. I plan to buy more of this model for my apartment. The quality is there, a nice heavy line cord to connect to the AC power, and better-than-average build quality. Slick!

It works but not so sure about the EMI/RFI noise filtering claim
Color: Black, Size: 8 Outlet, Style: Outlets Only
I only buy surge protectors that have EMI/RFI noise filtering. I have a sensitive short wave radio with a sleep timer that I use when going to sleep. It has a rechargeable battery so you can either use it plugged in or on battery power. I've always had static on the radio when it was plugged into this surge protector. Cords generally do cause interference in radios so I thought nothing of it. But it started to get really bad. So I took one of my old tripplite surge protectors with emi/rfi noise filtering and plugged the radio into that. No static or interference on the radio at all. I went to APC's website to see if this model has EMI/RFI and it looks like it does....but it sure doesn't work well on mine.
I don't want to disparage APC. I have several of their surge protectors. Just bought the big P12U2 model they have and love that one. I think it just has better circuitry than this budget model. I'm using the P12U2 on my TCL 55" TV that was flickering and was glitchy turning on and off with a different surge protector from another company. Anyways, the ACP P12U2 works great and appears to have excellent noise filtering. Just wish the P12U2 had a flat plug because I bought it to use for my computer, but couldn't because I couldn't push my desk up against the wall with that straight out plug. Anyways, I've strayed.
This is a good basic surge protector I suppose. Would not recommend it for sensitive electronics prone to interference. Then again, maybe I just had a bad one, who knows. APC is a great brand. All my surge protectors are either APC or TrippLite. Can't go wrong either way.

It Works
This works fine. Good size. Good enough cord length. Does what a power strip should do.

Great for multiple adapters
Color: Black, Size: 8 Outlet, Style: Outlets Only
One of the common flaws of single width strips is the inability to accommodate more than 1 adapter unless you want to waste the sockets as the adapter obstructs/covers
the adjacent sockets.
This one has 2 rows with sockets at 90 degrees. As such, adapters face outward and do not obstruct adjacent sockets. Well made and sturdy, typical of APC quality.
Hopefully the surge protection won't be tested but gives you peace of mind to know that all plugged in devices are protected. I have it mounted under my office desk using the mounting holes at the back.
Great value for the money.
