How we checked
The Magene official product page for the P505 Spider-based Power Meter confirms model identity ("Product Name: P505", "P505 Spider-based Power Meter") and lists the spec table used here (±1% power accuracy, ANT+/Bluetooth, IPX7, 200h endurance, Magnetic Base Rechargeable Lithium Battery) at a US price of $349.00. GPLama's dated (2022-12-21) hands-on review independently corroborates the same spider-based P505 with MSRP US$349, ANT+/BLE, IPX7, up to 200hrs battery, and a 2-year warranty. weight grams is left blank because Magene lists 110g as the total spider weight (S1078) rather than the added-weight-over-non-power figure the methodology requires, and measurement sides is left blank because a spider measures combined power and estimates balance rather than measuring both legs independently.
