Good quality materials and construction. Easy to mount with four bolts on the upper plate then two more in back plate. One of my best purchases ever. Also very stylish, but only time will tell how long it lasts.

Ex Output:
Good Review

Ex Input:
The story started out well for an erotic novel and got more interesting until the end. It just became a book of sex then love story. So I am in no hurry to read any more. Sorry!

Ex Output:
Good Review

I have had two sets of these speakers. Both speakers are extremely underpowered. If you want to hear a song in good quality, don't buy this speaker. You can get speakers with better sound quality for less that this product. The speaker design is very sleek and elegant though. Too bad the product just plain sucks!They looked great, but unfortunately they didn't perform well. To start off with, it doesn't match up well on my desk top,looks ugly next to it.
