Review on 🔋 Power Boost and Freedom with Marpac 90067 Battery Pack by Kenneth Seymour

Looks like it came in a sealed bag from the factory, but when I tried to open the battery compartment (after undoing the screws of course) it's not open. I noticed what looked like glue residue on one end near the power cord, and this glue stuck to one end of the battery cover. THE? I managed to open it but it looks like someone either broke it and sent it back, or they have a weird manufacturing process. I now think I didn't think about it before making this purchase because it's just a glorified battery holder. You need SIX AA batteries (at your expense) and decent batteries cost more than double. At the same time, some reviews here indicate how much uptime they can get from them. What a nonsense! Run time depends on what batteries you use, so it's useless for other buyers to turn them on and credit that empty plastic box for delivering that performance.
