The improvements made compared to the older units are HUGE! Not only do you still get the most amazing programs in the world of EMS, but now I have more programs and user friendly features that I love.

The snap pads are so easy to use! They make it much easier to attach the leads when you are working glutes and hamstrings in particular

The progress bars are very useful. You can tell exactly how long your contractions and rest are going to last which is very handy.

Being back lit is AWESOME! Great idea.

Being able to select which intensity buttons control increases and decreases is great. Most times I select ALL so I only need to push 1 button to increase intensity on all channels.

I LOVE the massage feature! This equates to the best massage I've ever had and I can do it anytime and anywhere. Talk about money savings! As a cyclist I pay for massages frequently when I'm racing. Saving this money will pay for the unit easily in the first year for me.

Charging is the only thing that is a bit less intuitive. You need to take all the cables out and then a guard pin is pushed aside to insert the charger.

Overall the improvements are very useful and much appreciated.

Thanks Compex!!
