It appears to be substantial
It appears to be substantial. I haven't had a chance to use it yet, but looking forward to trying it out.
The only issues I had is there was a black tube with a bunch of numbers but no explanation as to what it is. Secondly, I received 3 of the devices. Not sure how that happened. Did I accidentally order devices? Can I return the other 2 for a refund?
Thanks in advance. Gerry Page.
