DougR, P;ease note that I do not intend to insult anyone or start anykind of flame war.

There are two factors to be remembered before claiming that any system works

1) Repeatablility - Can you do it again (and again) with the same kit.

2) Reproducability - Can another operator, using the same technique reproduce your results.

From your post, at present there is, at best, a 50% sucess rate. Please wait until they can do it a few times without missing before declaring the whole thing a success (It could just be a luck).

Regards

Walrus
