I've had harmony remotes in the past and they worked well enough, but tended to suck the batteries dry fairly quickly. This one seems to have solved that by moving the power hungry parts into the base station. I like the slim, screenless remote as well. The old one (Harmony 650) was a bit bulky. The major benefit compared to the previous one is when configuring it. The phone app and wireless connection is sooo much more convenient than the old (Windows only >:( even though web based!) method! It used my old profile too and only required very minor tweaking to make me happy. It seems a bit faster as well, and the base station (maybe more powerfull iR emmitter?) seems to be more reliable in communicating with my gear. Overall, very pleased. It's a bit dear, but I think it will be the last remote I buy, so a good investment.
