Sounds like a good buy!

Also sounds well worth it if your DH can make use of it. Great idea to get some help from your physio, it is nice to feel you have a confident grasp of how to use it. Make sure you word up your DH properly too. I tried to get DH to attach mine when in labour second time around and he made one of the most fatal mistakes... after attaching the electrodes he turned it on without checking the settings with me and zapped the begeezes out of me. If I could have jumped out of my skin, I would have and it set of a major contraction, starting at a peak rather than working up to one. Not something I recommend or care to repeat!
