Suggested actions
These are things to investigate, not conclusions: - Mount: check returns or warranty data for three separate issues: a loose fit on a thin handlebar (R2: "mount feels a bit loose on my thin handlebar"), breakage (R3: "Mount snapped after two weeks") and needing a shim (R8: "The mount needed a shim to fit."). R8 does not say what bar it was fitted to. - Faulty unit: check the batch or ship dates for R6 (2026-10-14, "Arrived dead") and R10 (2026-10-28, "Support replaced my faulty unit within days"). - Battery life: R9 says "not the week promised". Check what the product page says about battery life and under what conditions, since R4 says "Battery lasts my whole commute week." - Support: R6 says support "never answered my email". Find that ticket. - Shipping time: R5: "shipping took 9 days". Compare it with the delivery times you state on the site.
