Is Tofisopam Too Good To Be True?

I recently found out that there is a benzo, tofisopam, that has all the good effects of a benzo minus the bad(withdrawal effects, drowsiness...etc). There are some papers about it, but no where near the amount you would expect considering its supposed abilities, anxiolytic with no withdrawal symptoms? seems to good to be true, has any of you ever tried it? For those that have not, I would advice you to some research on it, its a very interesting drug.
