Things I liked:I have not yet used the rifle. It seems to be well constructed. Things I would have changed:The owner's manual provided with the TF99P is the owner's manual for the Industry Brand QB36 air rifle. The TF99P and QB36 seem to be equivalent rifles, but wonder if the TF99P has an owner's manual. The QB36 manual has only a few words about maintenance and care. Plus, the QB36 manual is poorly written...the translation of Chinese to English is poor. I have not used the TF99 yet so I can't rate it's accuracy or performance.
