Apex Covert sight

Has anybody used one of these? Looks like it might be a great sight for the money. Hoping maybe I can get some feed back other wise I may have to test it myself. My local shop is a dealer but they don't have it in stock.
Here is a link if you haven't seen it. http://apex-gear.com/pc_product_detail.asp?p_key=746EBF1529204A56BFE18AA4F0354929&cat_id=

 

As soon as taxes are in, I'm going to buy one.

 

PLEASE let me know what you think of it when you get it. Of the single pin sights I've looked at lately this one has my attention more than any other. If my wife would leave me alone I would already have one!
