[EX Q]: Get the Otium Bluetooth headphones. I mistakenly bought these thinking they were the same because they look identical but they were not the same. Bluetooth connection would break up periodically. Sound was average and they broke in half when I pulled them out of my gym bag. Poor overall quality.
[EX A]: negative

[EX Q]: I wish I bought these sooner. I noticed a significant savings in just a month as I used to leave to lights burning 24/7 in the front and back yards. These LED lights are very bright in a positive way and help me to easily see my front driveway area as well as my back patio area in the back.
[EX A]: positive

[EX Q]: If you already have the DeWalt batteries his is a great addition. This fan is so convenient to use that I end up using it all the time. It moves an impressive amount of air while at the same time is quiet. A 6Ah battery runs for over 10 hours on high.
[EX A]:
positive
