## Description

desertcart.com : ASP D1 Insert for The Metro Defender D1 Pepper Spray, Pack of 2 : Bear Protection : Sports & Outdoors

Review: Great product, Good quality...Replace cartridges yearly - Great stuff, not sure the test vile is worth it but good to understand how it works. This stuff is the real deal with 10 percent heat vs a lot of pepper spray on the market. Do yourself a favor and look at percentages on anything before you buy it. Also you should be replacing the inserts once a year. The Pepper spray units last forever, had them on all our keys for 8 years and they still are great.
Review: Four Stars - Had a bit of a mix up with shipping but in the end product arrived as expected
