WEPS04 Wireless Bluetooth Pressure Sensor Transducer, 1/4”NPT, 100PSI - Made in The USA

Wanted to get the made in the USA product. It seems to be pretty nice construction. However, without a display, you need the app to work and work well...and it doesn't seem to work at all. It seemed my phone was able to connect with it on Bluetooth, but when I'd open the app it just says "searching" indefinitely. There are a couple different apps of similar names (each $5 mind you); I tried both and both failed to ever connect. Couldn't find any troubleshooting resources on their website. Only plus side is they at least refunded my app purchases. Maybe you'd have better luck with iPhone but it was a dud on Android.
