Review on DREAM SPORT Bike Computer Cadence Sensor - Bluetooth & 🚲 ANT+ for Spin Bike, Speedometer Zwift, Garmin, Wahoo, APP, Stationary Bicycle by Jesse Diaz

I usually use non-magnetic Wahoo sensors. I've used both Garmin and Wahoo magnetic sensors and have found non-magnetic sensors to be less of a hassle and nearly identical in accuracy. A little less accurate because they rely on accelerometers and averaging calculations, but very close (close enough). I decided to try these DREAM SPORT sensors because they are cheaper than the Wahoo sensors I use. This is a rebrand from Taiwanese company Top Action. In fact, Top Action is still on the packaging and in the instructions. They are almost identical in size to the Wahoo sensors. They use the same CR2032 batteries but use rubber bands to attach the plastic sensor to the bike (like a 1/4 turn bike computer mount) unlike the Wahoo which uses a special Speed silicone band and either double-sided tape. or zippers at the cadence. The straps work well for changing the battery, but can be an issue if they are too loose on the bike. Over time, they weaken and need to be replaced. Hopefully not while driving. I was able to connect these sensors to a Garmin 830 bike computer, a Fenix 5 Plus watch, and a phone (Galaxy Note9) through the Wahoo apps. The weird thing I found (which is part of the reason for the loss of the star) is that the speed and cadence sensors report themselves as a combined speed and cadence via Bluetooth. ANT+ ads are correctly displayed as individual sensors. It would be nice if S/N or something else was included in the promotional name to identify them (which BLE has), but if you're just setting up a set then it's fine. I prefer ANT+ because I usually have a more stable connection with my devices compared to BLE. To test these sensors, I attached them to my bike with the Wahoo sensors already attached. I then went on a pretty long bike ride with my family (51.6 miles total). I used my bike computer to track the Wahoo sensors and my phone (through the Wahoo Fitness app) to track the DREAM SPORT sensors. Now 2 apps didn't start and stop at the same time so there are slight differences in the records but for speed Wahoo said I peaked at 25.8mph and DREAM SPORT at 25.5mph. The average speed difference between the two sensors was just 0.2 miles per hour. So overall it's very similar. Now that I think about it, I had to track with a third device that only used GPS speed. Spring. In the pictures DREAM SPORT sensor values are shown on the left and Wahoo sensor values on the right. To be honest, I'm having a hard time deciding whether to buy these instead of Wahoo's sensors. They appear to be similar in accuracy and they are cheaper. However, Wahoo sensors do occasionally receive firmware updates, and I doubt that will be the case. So, despite the cheaper price and similar accuracy, I'll probably have to go with Wahoo's sensors for their upgradeable, slightly more secure mounting, and weird device displays when pairing.
