5 of 5 Great Flashlight October 30, 2023
Reviewer: Portia from Hagerstown, MD United States  
I really like the flashlight. It was as good as I had hoped. I thought shipping was fast. However, I did have issues with the website when I was placing the order. I had to come back the next day because I couldn't get this site to communicate with the PayPal payment method. I also didn't get a shipping notice. I logged in to find the information.
