The pattern is clearly wrong. The screw is NOT M4-0.7 as stated, but M4-0.8. It is impossible to find suitable or replacement screws - nobody makes them. Why do it so clumsily?! Since you can't screw anything to the piston (unless you use a rubber bulb to do it), you can't use it as a locking ring. Another misleading point in the description. Other than that, it's the same cheap lamp that everyone sells. No better, no worse. Suitable for the delicate PUSH clip.
