Anyone have one of these power meters for their trainer? I saw them at REI this weekend. Is it worth it?

Well, if I were you I will look also at trainer road (http://www.trainerroad.com/) it works on the same basis, but trainer road will give you more information, you will be able to save it and see your progress and it works with lots of other trainer brands. It is 10 bucks a month so on the long run you will pay more but if you dont like it you only spent 10 bucks and thats it, you will need the speed, cadence and ant stick though (that you might already have if you use a garmin computer), good luck.

How does it measure 'power' without any strain gauges? Why not just use a CatEye Double Wireless (or similar bike computer) that measures speed and cadence.

It is calibrated specifically on that trainer resistance unit, they know the power curves based on the speed. Something like this:

Yes, I saw the manufacturer's literature. Nevertheless without strain gauges, it is just a guess. How accurate is questionable. Your hard-earned money is better spent elsewhere.

I dont have experience with this particular product, I do have experience with trainer road that is based on the same principle and I've found that is accurate enough compared to my power meter.

Here is a review I found of the kinetic inride power meter

http://www.dcrainmaker.com/2012/12/kinetic-inride-bluetooth-smart-power-meter-accessory-in-depth-review.html

You can see there how he compares it with trainer road and a standard power meter, in DC Rainmaker's words:

"If you already have a compatible Kurt Kinetic trainer, then the inRide is a relatively cheap method of getting fairly accurate power measurements for it – at least cheap compared to a full blown direct force power meter"

That being said I think that having a power meter is a better investment on the long run if you like to get into numbers, specially now that the powertap got "cheaper".
