First Round Verdict
The only power bar in this first part that truly distinguishes itself from the rest is the Sunbeam, which deserves do not buy recognition due to its unsafe MOV. If this happens to be a counterfeit unit, at least you know they are out there and need to be extra wary about them.
The Noma is clearly overpriced for what it is compared to its flea-market twin: a 60cm (2') longer cord and a 20D instead of 14D MOV are not really worth paying an extra $7 unless you absolutely need the length and have no other options.
If childproofing your power bar is high on your priority list, and you're alright with replacing high-traffic bars regularly due to worn-out shutters, the BlueDiamond's PowerPro might be worth considering. But otherwise, the EL-543 wins this round as a device that gives you extra outlets to plug stuff into without being an obvious safety hazard.
In the next installment of this series, we shall take at products from more popular computer and power accessories brands.
