You can say it any way you wish. Being confrontational about such things will not win over any converts.

Voltwatch2 works just fine. You use your product and those of us that have been usiing Voltwatch2 for quite a while now will continue to use ours.

Now, if you have something concrete to back up your claim, then come on.. tell us, but be a bit less agressive about your approach.
