    Good product. Seems to fit and work. Certainly looks much nicer than the old yellowed one. Swap was simple. Use a 30mm socket with extension and tap in with hammer.

    The sight glass arrived quickly. My install was on a 99 R11S so I did not need the retainer o-ring clip that came with it. Once I removed the old leaky plastic sight window and cleaned the opening, installing the new window was straightforward. Fit is very snug; which is good considering it is only held in by friction. The window and glass assembly is of great quality and looks well made. I did notice that there were fewer holes (only 4) in the backing plate compared to the original and the one depicted online, but I doubt that would affect performance, infact the new one appears more substantial. All in all I am very pleased with Wonderlich and the sight glass.
