I am obsessed with this tool!! I love the convenience of having a pocket knife but hate the bulkiness. I also don’t carry a purse so i like to stack my phone with as many features as I can. The wallet and tool module have been amazing!! I always impress everyone around me when i whip it out- nobody expects it and always admires how cool it is. I also haven’t seen anything similar on the market. I will say having both modules and a cover plate on my phone do add some weight but I have gotten used to it. Also, I got a bunch of my family these utility mods for christmas but note they do not come with any adhesive to connect to your phone and ohsnap does not sell the adhesive part separately (I got mine when I bought the essentials kit). My dad ended up supergluing his to his phone case but this is not a good option if you need to remove it for any reason. I have my wallet module superglued to my case and the tool mod is magnetic and I can remove if necessary. Overall, I love the product and have literally been a walking salesperson for ohsnap!
