I've had no issues with tracking on mine (2.5-16x50), and the glass is very good for it's zoom ratio, price, and era (purchased in ~2005).
It served for about a decade and 2000 rounds on a 7mm Mag, 308 AR, and various other duties, before it had problems with the parallax adjustment. Sent it in to Bushnell, fixed for free and returned promptly, with no questions asked. Since then it's gotten quite a bit more trouble-free use as my spare scope for whatever rifle needs one at the time.
All in all it's been a great scope. Modern offerings of similar price point seem to beat it in the features department, but that's to be expected.
