I ordered my second pair of X-Bulls the other day (I ordered the first pair to see if I'd like them - and I did), and they arrived today (that was quick), so now I have two pair (four total) in olive green. So now I am a real Overlander (said tongue in cheek for those diving for the reply button). I've never used any of these things before, and other than internet videos, I've never seen any used in real life (we always used winches or snatch-straps). But I was watching one video where they used them in snow, and he ("Clay" - the famous expedition guy) said how it was so much more safer and quicker than pulling a winch (and in this case, a snatch strap wasn't really an option). So I was sold on the concept after that. But not enough to where I was going to spend over $600 for four of these things (hence the X-Bulls).
I would never say these are in any way better than a MaxTrax other than they are much less expensive. On a lot of posts, folks with the X-Bulls have nothing but praises for them. And I've never read anything bad about the MaxTrax. I guess we'll see first time I need to pull them out and use them. I do know you can buy three (almost four) pairs of X-Bulls for one pair of MaxTrax.
Right now they're on the Jeep's rooftop basket, but I'm going to make a way to mount them on the top of my lil' trailer (under the RTT). And if we take the wife's Subaru (Crosstrek) up into snow country, I'll either toss them in the back, or strap them to the roof for just-in-case.
The X-Bulls today also came with an unexpected gift - a little folding Army shovel. Perfect for tossing in the back of the Subaru (in the back under with the spare tire).
