If the technology seems as promising as Apple's AirTags, it is definitely not. The connection with the chipolo is sometimes lost. I had to proceed to a factory reset to get it back up (thank to the Support Team). However, the Find My Device app is quite inaccurate, and regurlaly shows me the loaction the device had 8 hours. Not very helpful. I don't what is to blame (Chipolo or the buggy Google App), but it is neither a sastifying nor seamless user experience.
There is a possibility to track my chipolo without Bluetooth BUT at the moment only if some android devices with the right settings are around. And that is often not the case right now.
