LOVE THE FLAK SACK II & LOCTOTE

I am so happy with my purchase! The product itself gives me peace of mind and I can rest assured knowing my important items are protected. The company is great, shipping was fast, and this bag turns heads. Every where I have gone, people have asked for specs and where they can get one. I have officially retired all my 10 of my cinch bags, because LOCTOTE and FLAC SACK II won me over. I recently went to the arcade with my family and my kids wanted to go skating on the rink with them. It was so easy to just hook my bag to the bottom of the bench and have a blast with my kids worry free. I appreciate the follow up e-mail, and as a consumer the entire experiance has certainly been a positive one. Thanks LOCTOTE = )
