I prefer the ced7000 over the ruready model, we had 2x ru redies and both failed after less then a year of service, plus the hassle of 9v batteries (think they should have a "AA" or a CR123 model), also it took a year to get the monitors returned after repair from RU Ready in Ontario.
The 7000 is rechargable and yes out of the 3 we own we have had one fail but it was less then 10 days and ced had us a new one (the button on top stopped working, the actuator broke off the motherboard inside) so yes they break but CED has AWESOME customer service.
some other things I like about the CED 7000 is that they have skins for them so every timer can be a different color, the ability to link to a sky screen and the ease of use of the newer models when set in "RO" mode, also ced has different clips, cables, lanyards for mounting this thing anywhere you could ever want it and the beep is loud.
