Same experience for me as well - fantastic if I'm extremely tired and need to be awake and semi-productive for an entire day, but does basically nothing for focus. Not even remotely comparable to Adderall. Also like others have mentioned, you need to be careful about when you take it (as soon as you wake up if you want to not sleep like shit at a normal bed time), and if you take it for more than a couple days the come-down can be rough.
