iGPSPORTBSC100S GPS Bike Computer Wireless, 2.6'' LCD Display 40H Rechargeable Waterproof Cycling Computer Bluetooth ANT+

I am a retired senior and I started riding bikes about 2 years ago. This small bike computer has been a game changer for me. I have only had it about a week, so reliability over time is an unknown. It picks up the satellites quickly and appears to be accurate, as I have nothing to compare it to.I really like the fact that it shows me my miles ridden as well as the average mph. I currently started riding about 27 miles a day every other day. The readout is fine and living in a southern climate with a lot of sun, I wear polarized sunglasses and can see the screen very well. It also came with a bonus which was the handlebar mounting unit which makes it very convenient.About the only thing I can comment that may not be accurate is battery life. My ride usually takes me about 2 hours, and in that time the battery seems to go down more than I anticipated. The battery does not give a numerical readout, but rather shows a battery icon with marks. It seems every few rides drops the battery level to a point that I really question the 40 hours of potential charge that the seller indicates. I only charged it 1x or 2x, so I will need to see if it settles down and I should be actually getting about 20 rides out of a charge.I am obviously not a competitive biker, mountain bike, etc.. I only say that as there are many more expensive and feature laden bike computers available here at Amazon. I ride within my community on the same "circuit" so I did not have the need for more extensive features.Overall, super happy with this computer. I hope it lasts a long time.Update:I've now had this a few weeks and it had "frozen" in the middle of a ride. The buttons become unresponsive and only resetting the computer brought it back to life. I then lost ALL the information stored in the computer and had to set the computer up from scratch as if I was just using it for the first time.I contacted the company and they contacted me within 48 hrs. They suggested the "fix" was to reset the computer, which worked. I rode about 30 miles right after I reset the computer and it worked fine. I'm hoping this was just a blip. The company did offer to replace the product if the fix they suggested was unsuccessful.

It's easy to mount and looks great. The simple sunlight-readable LCD display (also backlit at night) reminds me of the old wired wheel sensor ones we had as kids, but it has so many more features packed into it. It has GPS, connects to your phone with bluetooth to their app which will link instantly with Strava, and if you want more data, can connect to any standard wireless speed, cadence, and heartrate sensors. Battery life seems great. I haven't run it dead yet, in fact any ride less than about 25 miles and it won't even drop by a bar. No comment so far on durability, but it's really lightweight and plastic, so I imagine a drop wouldn't hurt it. I did one ride in pouring rain and it's definitely waterproof. It's pretty easy to use once you get the hang of it, only has two buttons which do different things whether you're in a ride or not. The manual is pretty short and simple, maybe too simple with some Chinglish, but it gets the job done. One note: When they say diameter, they mean circumference ;) No routing capability that I know of and no fancy color screen with map, but low price and high battery life are the benefits you get by not having those things.

It works. The setting menu on the device is not very intuitive but that aside it works as expected.

Pros: I lost my wahoo bolt in a move and didn't want to shell out so much money for a new computer so I got this one. It meets all my current needs of being able to connect to my power meter, syncs with strava, auto pauses, auto back light, etcCons: The only features its really missing is GPS navigation and strava segment data. And I don't like how I can't fully customize the pages how I want. Each box has a designation of what is allowed and it's not really laid out well. But can't complain for the price. The app is kinda annoying as it shows an ad when you open it, but its not a huge deal. I was able to set everything up with the app pretty easily. iPhone FTW. Android may have issues as usual.Can't comment on durability or battery life yet as I just got it, but it seems well made overall. The rubber band mount was super annoying to figure out and the manual that came with it is pretty much useless. But i did a google search for bsc100s english manual and found a manual on a website called datadepo and that got me going.Overall I would recommend.

I'm pretty happy with this little gizmo. It automatically tracks my rides and uploads them to Strava. It gives me the info I need for my ride. It does not do GPS navigation, but I ride the same trails all the time and generally don't need directions.
