ASP-680, ASP-682, ASP-685 & etc.

Anybody have experience with them?
How they in comparison with RFS/Celwave, Sinclair, Procom, Kathrein & etc. base omni fiberglass antennas?
It's correct that they originally made by Antenna Specialist? I do not trust Antenna Specialist production as it is similar to cheap Chinese toys (if to speak about mobile antennas).
Any info about will be appreciated!
