PowerPod V5 Power Meter + PowerStroke Upgrade

Update to my prior review:

Before reviewing the Power pod, a quick review of Power Meter City, this was my first purchase with this company and I am in Canada so there is always hesitation before purchasing online and across borders. My experience with PMC was very good, they updated me on my order during the initial handling period and the delivery was very fast and without event. My initial questions (emails) with respect to setup were answered almost immediately and they followed up with me to ensure my success with the product. I highly recommend Power Meter City as a vendor.
I have now had my unit (PowerPod V4 with Powerstroke) installed on the bike for a few weeks and have had the opportunity to play with it. I have no experience with strain gauge power meters and I am an older rider with no aspirations of becoming Pro.. but I am technically inclined and have a good understanding of cycling. I am comparing the power values with my smart trainer (Rouvy/Zwift) and all I can really say is that it feels comparable. The average power read while riding outdoors is almost identical to what Strava “suggests” that my average power was. For me, this is what I am most interested in, a live indication of my power output.
My complaints with the product is that the documentation for tweaking almost doesn’t exist, there is some online information on the PMC website and on the Velocom website, but not a clean document, the calibration card doesn’t seem to be fully compatible with this version of software in the unit. Most of the information on the web is about older versions of the Power Pod, and most of my useful information was directly from the Velocom forums, reading what other users have experienced. As most the information available is about the Power Pod V3, anything I read there I had to test whether it was applicable to my unit.
But as I get more experienced with my unit, I am getting happier with it.. the numbers are consistent which is most important to me. Another important point is that I am primarily a road cyclist on asphalt, I have noted that the unit seems to be off if you start the ride on asphalt and ride on to a gravel road, the section on the gravel seems to be low… I believe because the rolling resistance is much greater. I am still playing with this, but it maybe a consideration if you are a mountain bike / gravel bike rider that variability in terrain may affect your numbers. I remember reading one of the forum threads which suggested that the device may change profiles while in a ride.. now I just have to rediscover that thread.
I am happy with this purchase, it is considerably easier to install on a bike and cheaper than most power meters, the data seems consistent and the software (Issac) provides a lot of numbers to explore.
It has almost seamless compatibility with my Garmin 530 computer. It is important to note is that I am technically inclined and thus enjoy the challenge of setting up/tweaking the device with limited input, but right out of the box, it had fairly close numbers.

The money you save by buying this power meter will be wasted in the time that you spend trying to get it to work properly. It is a very finicky device that requires constant recalibration, resetting, tweeking on your computer, and good luck getting it to work well on two different bikes. Cycling is a time consuming enough sport, I certainly don’t need to spend 1-2 hours extra per week babysitting bike electronics.
