The reviewer provides a comprehensive analysis of the Magene P715 power meter pedals, having tested them for 3-4 months. They state these are currently the most affordable power meter on the market at $499, which is about 40% cheaper than competitors like Favero Assioma. The reviewer conducted comparison testing with other power meters and found the P715s to be consistently within 1-2% accuracy, which they consider more than sufficient. Key features highlighted include 120-hour battery life, availability in both Shimano SPD-SL and Look Keo standards out of the box, claimed ±1% accuracy, 157g weight per pedal, and inclusion of smart metrics like power phase and riding position detection. The reviewer notes the pedals lack pedal center offset (PCO) capability and don't include cleats in the box, but concludes these are minor issues that don't significantly impact real-world performance.

The Senicx crankset are solid, and probably the cheapest way to get 165mm crank arms these days. Though as raisinberry777 suggests, you can pick the PR2 DUB model, which saves some weight.

"Why risk buying cheap stuff from abroad?"

We love new bike tech and follow bike brands extensively. Riding bike can be a very price intensive thing, but it can be made more accessible by saving some money, and spend it on the parts that matter mostly for you. After a couple of thousand kilometers, most buyer can determine the quality themself. YouTubers, like TraceVelo already have a successful history with using cheaper parts from Aliexpress or eBay. To crowdsource those experiences, we've made this site, to seperate the wheat from the chaff. To be honest, there is also a lot of crap or mediocre stuff out there, but at the same time you can find reliable and quality stuff.
