I've been using this for several months now. The steel or titanium option is great. I have 4 keys, each a different size. Works great, keys stay in place. I only had to readjust the screws once. I used some Loctite to hold them in place. I haven't had to add or remove keys yet, and I have small felt washers in case I ever need to add more keys. high. I preferred this model to more expensive models with plastic, battery or tracking. I wanted simplicity, not another thing to charge or worry about burning in my pocket. I have a car keychain, a gym keychain, and this keychain. This simplifies the task: I use two keychains with a car key so that it folds better and adapts to carry in the pocket. I've found that using just a key ring with a key fob doesn't offer flexibility or convenience in my pocket.
