The Protek PR-91W has poor documentation, a rudimentary IOS app, a rather annoying flashing power button (possibly related to the app installation/syncing), and an extremely bright display that cannot be properly dimmed. It does work reliably, has two outlets for amplifiers which presumably won't limit the required peak wattage. I like the idea of EMI / RFI noise filtration, although such filtration is likely already taken care of by the circuitry of the individual audio/video equipment. I feel better about the safety of the protected equipment, and it does provide a sense of improvement to the background noise level, even if it doesn't actually contribute to it.
Pros: many outlets, clear display, appealing slim form factor
Cons: poor documentation, simplistic app, dispay too bright
