I think it really helps to take the edge off the contractions, and is fantastic for managing early labour!Goodluck
That's a very good point - get it on asap. I got to 8cms at home before I felt like I needed to go into hospital, could barely feel the contractions with the TENS on at this stage.

The only time I got panicky was when I couldn't get it to work. Definately worth getting.
LOL you just reminded me when my DH was changing the batteries (theres a tip - take spare batteries with you!) and I started freaking out because I could feel a contraction coming! Never seen a man move so fast!
