Verified Purchase
helps locate cars while biking
I don't know the current situation but when I bought this radar unit it was heavily discounted vs other units that also included a light. The radar feature works great and I really like having it when I bike. O-ring to mount it on the bike seems like a bad idea but for now it works ok.
Was skeptical, but a great item
I've been putting off buying this as I figured it couldn't be that great, but I've been really surprised how quickly I've become dependent on it during road cycling. Very accurate, rechargeable and works on Wahoo as well as Garmin (of course). Very happy with the product.
Be Safe
Ordered two one for me and one for my wife, one worked perfect but the other one kept stopping and putting out an error code. Contacted Garmin and was told it needed to be replaced. Return could not be easier. Ordered a replacement, ride with peace and could save your life. Hard to hear an electric car!
