Had one on my 2001 (picked it up in a trade) and found it to catch less on slings and such when donning/doffing gear as compared to the issue NOD mount. Other than that I really didnt notice much of a difference.
I highly doubt I would ever purchase one out of my pocket though...
If you are looking for a replacement to the issue one, I just picked up an
ops-core VAS shroud for a replacement to the Norotos (someone wanted my 2001 more than I did-I hate thieves.) I have found it to be comparable to the Norotos mount at a fraction of the price. However it does require you drill a couple holes to attach it to your skid lid...
HTH,
