Rated 4 out of 5 by Brian26 Good product, could be improved.
Good timer product and relatively easy to program. The backup battery is a CR2032 Lithium cell, with a 3-year reserve. Sometimes you may receive the product that has an internal battery that's near it's end of life, and the manufacture does not recommend the user change the battery. I have changed several batteries in these units but you have to be extremely careful not to damage the plastic clips that hold the unit together. So what happens when your backup battery expires? Most customers may have to throw the unit away and spend more money purchasing another unit. This battery should be made to be user changeable, after all, the manufacture produces a similar timer that's an intergal part of a four function Air switch that has a very simple user changeable setup incorporating the exact battery. The instruction and programing manual could be improved, certainly the size of the printed material. The timer is a bit high priced, especially the 240Vac versions.
