they better than nothing joe.
there the same ones me and tom used on road trip 2007. they were ok, but we found their limits pretty quick.
we bought some great ones for 2008 but there from america, and are a lot stronger and using them in europe requires a license. oops!
anyways..they were great obviously anywhere in the world, but they work on different frequencies that the normal ones you'd find in the UK.
and as ive only got two, it would be pretty useless bringing them too
