Understood. While I agree with some of the comments, Edmund and I know these remotes inside and out and can help as needed. The Inteset works fine with Roku 3 and all other Roku models. The reviewer must have inadvertently wiped the remote's memory.

The other comments are due to ignorance. We can point you to good documentation, software and procedures that the reviewers are unaware of.

Harmony remotes are great and very simple, but much more expensive. However, a decent refurbished 650 can probably be had for around $40 and meets all your needs, if you're more comfortable with that.
