    Excellent safety upgrade for cyclists

     Adding this SR30 tail light radar to an iGPSport computer is a few clicks on the settings menu.  It shows up immediately and just works.  I bike commute and my route includes a decent bit of road where mirrors help but eyes front is necessary for busy intersections and traffic lights.  The beep tones from this radar are just what I need to discern if someone is coming up behind me to beat a light and bump me into the ditch.  There's visual clues too but the beeping is really enough.  The beeps are somewhat like handheld games from the 80s.  They are easy to hear over traffic sounds and the patterns are such that they aren't akin to any other beeping thing on your kit.  The volume isn't so low you can't hear but also not so loud that it gets to be obnoxious when you ride in traffic.  I wear a Monster Boomerang on my neck so I can listen to tunes but still hear the demonic shouts, beeps and revved engines of angry motorists.  If you wear earbuds you may not hear the electronic tones but that depends on your settings and computer.The radar is extremely sensitive.  It really does pick up cars that are lanes over and can discern ones that make a more menacing approach.  It seems to be able to tell large trucks from cars too.Installation is easy.  Generic O-rings of various sizes keep the brace in place on your seat post.  Future replacements are simple because O-rings are available at most hardware stores and online.  Charging is USB-C so no special cables to label and misplace.The brake light is bright and it appears to go to sleep when there's no motion.  That's important for me since I'm usually in a hurry when I get to work and I forget to turn off the tail light on my bike.Battery life is decent.  I haven't had it long enough to incorporate into my charge routine at work but it's not yet died on me.  The unit is fairly large and a bit heavy which is likely more about battery size than anything else.  I'm happy with that compromise.For my review I'm using the iGPSport BSC300 -- it's currently the best low priced bike computer with high end features.  The combination of the SR30 and BSC300 is an excellent way to level up a ride and not break the bank.

    Good value.  Helpful alert display on Garmin 530
  

*by J***K on Reviewed in the United States on July 18, 2024*

Works as advertised.  Easily paired with Garmin 530.  Radar not blocked by cyclists behind me. Eye catching red vertical bars on Garmin with moving ball showing approaching vehicle.  Adds a second ball for a trailing vehicle, an issue using my eyeglass mirror.  Bars turn green as last vehicle has passed.Great value for a significant safety aid.
