A matching Vixen-style dovetail clamp is available for additional $50 (if bought together with mount).
The Astroslew II has 4" teflon friction pads and made from a high quality solid T 7050 aluminum alloy (more strength than the budget version of current Astroslew), can handle more load than version I and III.
See here for more details: http://www.singastro.org/viewtopic.php?t=3709
You can try the mount for two weeks, if for whatever reasons you don't like it, you can return it in same condition for a full refund.
cheers,
