There are no real problems, but let's say 1.5 Weaknesses: firstly the shoulder pad stays in place permanently, which is annoying in the long run. Secondly, I was annoyed at such a high-priced product a little bit about the fact that it can not be produced in Germany at this price, but must come from China. An objective is the weakness but not because of the quality there is to my mind no complaints.
Edit
to the "1.5 Weaknesses" a serious new has discontinued with me: the sniper completely dissolves despite constant and conscientious control of the fixing screw - if you're unlucky. Mir is a camera equipment has been dropped, and even though I the manufacturer's instructions, to regularly check the correct fit of the screw, conscientiously - have fulfilled - if not to say "obsessive". Of course I would have in the seconds before the fall again to check the fit, but an inspection by the minute, is not reasonable.
I must therefore unfortunately this issue to be very pleasant harness the testimony, that it represents a serious threat to any camera equipment and therefore an absolute no-go's. There are also attachments via the tripod socket firmer brackets, with whom I have had very good experiences.
In my case, the equipment was insured, especially with many amateurs a camera but insurance does not pay, so that a fall of the camera is much more annoying.
Edit 2
The problem of solving screw I have now solved that I've replaced the screw of the sun sniper through the bottom plate of the Spider Holster and the D-ring (also about Spider Holster to relate). Via the ring to the hanging sunsniper directly to the base plate and has a - as I see - bomb fixed connection. Besides increasing the base plate also the comfort of the sun sniper: First, it is flat to the camera and presses for upright shots not in the hand. Second, it comes with its own tripod thread and must for shooting with a tripod not need to be unscrewed, which indeed was previously necessary when sun sniper.
The first inserts the combination absolutely perfectly, ie survived without wobbling or tightening. The base plate I use for quite some time in connection with the Spider Holster and have won a very good impression of the strength. Of course I do not take guarantee for this tip, but if anyone should have problems, but I am very pleased with this very safe and comfortable solution.
