Diesel injector cleaners - any good?

As above, do they actually do anything? If so, which is best?

Have a look at www.bgprod.com . We use it on all services. Have a look at their guarantee, it suggests that they have confidence in their product.
They have run a similar scheme in US for a number if years.
