I am doing some research on the Power Meter segment and some of the products which exist in the space, particularly in the demand response and the preventative maintenance space. Some of the better devices I've come across are the Dent PowerScout3 and the EIG Shark 100/200. Does anybody here have any experiences with these devices or the Kele EnGenius?

Any thoughts on products or experiences you have had in this space would be great. Thanks
