Literally just bought this UNI Mod today was able to get it to work for about 5 minutes and now all it does is display the 5 blinks lights every time button is pushed. Connectors have been checked along with multiple cartridges and it is fully charged. Is my product defective?? Super disappointed with the product so far.

Hi @milo1618
Please check the cartridge connection with the UNI battery.
5 blinks means UNI can't find your catridge.

Any further question, please let me know.
