Product review (4 stars): Better than the original sprayer arm.
The original top spray arm in our Bosch dishwasher kept falling off.  I would snap it back in but it would eventually fall off again.  This new version has a more robust set of clips.  I had to take out both the top and bottom rack to access an pry off the mating connector at the back of the dishwasher, but it too is more robust and so it was worth the effort.  The new sprayer works great and should last longer than the original part. Only gave 4 stars because the included instructions were a little vague but I figured it out in short order.  I'm sure there are videos online that will help the technically challenged be able to DIY the process.  Took me about 20 minutes and the only tool I needed was a screwdriver to pry off the back connector. Good upgrade. Very happy with it.
