10 out of 10Feature:
One feature...it gets rid of the hum, what else do you want?
Quality:
It a little tin box....I wouldn't go dropping it on the floor, but I'd say it would survive.
Value:
Half the cost of the others, and it delivers.
Desirability:
It's a box...how sexy can it be?
Sound:
Totally eliminated the hum...and my application is sort of non-standard. I haven't a CRT monitor and I do a lot of recording. Well these put out a very large EM field and will caused your pick-ups to pick up a lot of hum...this thing did the trick.
Ease of Use:
Just plug it in and it works.
Support:
Not on this product, but Behringer make good cheap products. I own their DUALFEX Pro & PowerPlay Pro.
Overall:
Perfect for the application, made good on its promises and solved the hum.
