Miami had a great vibe - everyone seemed super fit and relatively ripped - a lot of the guys had their tops off and were showing off their 6-pack. I loved running along the beachfront (see recent post).
It was quite an expensive area and there weren't many (if any) bargains, however I did find a Garmin Varia RTL515, rear light plus radar, on a special deal and even after the local tax, still at a decent discount to what I could get in the UK.
Anyway, it was a nice holiday treat so I jumped in.
My first impression is very positive - it simply provides a good visual representation of cars behind you, how fast they are approaching, when they overtake you and how many vehicles are close by. All without looking behind you. I definitely feel somewhat safer, or at least more aware of what is around me. Thumbs up, so far.
