They're probably fine. I just don't shop at Monoprice. I find their website a jumble, and even when you do find a part that will fit, you don't know exactly what you're getting. I feel this way about every place I shop. I usually know the manufacturer's part number of what I want, I've gotten all the specs I need from the source; it's just a matter of finding a good place to buy it.
When I'm looking for something more generic, like wire, I often have to rely on the reseller to tell me what I'm getting. Monoprice fails in that respect, by providing next to zero technical information. Including statements like:
Monoprice continually strives to improve its product line to bring our customers the best products available. Therefore, changes may be made to listed specifications without prior notice. Item received may not match photo or specs shown.
...makes me run away screaming.
But that's just me.
