What to know before buying

Listing details to confirm

Battery details are inconsistent: the listing calls the unit battery powered and says two LR44 batteries are included, but also labels it rechargeable and lists 120 minutes of battery life. The product description separately claims auto shut-off, but no operating conditions are given. Confirm the battery setup and runtime before buying.
