Query: Why are you reading reviews? Just buy it...

I wasted several minutes reading reviews and comparing this unit to others, when I should have just thrown it in the cart.Works great. Picture doesn't show it, but the plug is three prong and the grounding prong is on the bottom of the item as pictured. Third plug follows the pattern of the first two, so you wouldn't be able to use the unit with three bulky chargers (though you could fit two chargers and a small plug). Small and nicely durable for travel, as other reviews have mentioned -- if you're always looking for a free outlet in a cafe or airport, bring this along and create your own!
