[EX Q]: I didn't have a bottom rail on my rifle so I needed to go get a bipod mount. After that it was easy. Would be nice if it had the option to get a rail mount piece or a bipod mount piece through the order. But I love them, they are strong and easy to put on and use.
[EX A]: positive

[EX Q]: Arrived promptly. I received it today and began taking immediately. It contains so many vitamins, such as A, C, D3, E, B6, Folic acid and of course biotin, etc. I believe in this product and hope it will deliver promising results.
[EX A]: positive

[EX Q]: I just received this lotion and the pump will not work. I will have to unscrew the entire top with the pump attached , which will make a mess. That's why ordered this product because it had a pump.mi was going to mix this with my alpha hydroxy lotion for my all over body moisturizer. I hate to go through the hassle of returning products so I will try to use it up, but would not order it again unless it has a lid.
[EX A]:
negative
