The unit seems to work fine when pointed at a slight angle to a receiver. I can control from up to 15ft away if I get the angle exactly right. It does not seem to like being pointed directly straight on to the equipment but at a slight angle off center works better.

Thus the emitters must be working. I am unclear as to what type of defect would cause it to work less reliably at an certain angles.

I do have a rather severe angle to two pieces of equipment that I have problems with most often.

It is just that the 880 handled that angle well but the One does not. I am not so much wondering if the unit is defective as I am looking for a confirmation that the spread angle or intensity of the Harmony One is less that that of the 880.

Anyone using the Harmony One felt the need to add an IR repeater. If so any recommendations?
