Hi Jack,I have one and find it ok.Make sure you detatch it when you finish your run for the night,in winter (with frosty mornings)the ambient temp will cause it to detatch during the night,fall and damage your vehicle, possibly.Other than that I have found it good.I bought it for my second vehicle(new Hilux)when I cannot use my hunting swb toyota.Handle length will depend on your rig and comfort spot out the window I guess.For what they are worth I recon they are a good investment.I found that I needed to adapt it too suit the lightforce swivel arrangement, as I use the lighter one("T")The big one is a straight bolt in job.No real drama though if your a bit handy.Hope this makes some sense.Oh yeah,give the cups a bit of a lick,and make sure your roof is clean.
Cheers,SMITHY
