If storage space and functionality are your concerns, you can't go wrong with these two USB stick packs. After a few hours of use I only got one connection error and that was fixed by simply pressing the drive (probably my fault for not fully plugging it in). Build quality is good, not great, and I don't expect it to last me for the next 10 years. You can technically attach it to a keychain, but the metal is brittle and I removed it from mine to prevent them from coming loose. Overall a good product just not as wearable as advertised.
