Wireless GPS Bike Computer for $20.15!

AliExpress has the ROCKBROS GPS Bike Computer for $20.15 after applying the coupon code JJZ03D at checkout. The device features wireless GPS, auto-pause, a waterproof IPX6 rating, and a 20-hour battery life. This price is close to the lowest we've seen for a GPS bike computer with similar features, especially considering it ships directly from a US warehouse, reducing shipping time and cost.

The deal's modest discount and the non-abled to compare against a full retail price suggest this is a good value, but not an exceptional discount. Still, the price point is competitive for a device with these specs, and the deal's popularity (496 views) indicates user interest.

This deal is alert-worthy due to the affordability and features relative to market options, but the actual price drop isn't large enough to warrant an A grade. The need to be signed into an AliExpress account and apply the coupon are minor hurdles but don't diminish the deal's value.
