It works fine

It set in snug and adjusts flush. No complaints, cheap and it works fine with my Freud Dado stack. It's not for wide stacks but that is a good reason to go out and buy a 14" "shop" table saw.

Dado Insert No. TS 1007 for Bosch Table Saw

This is a metal dado cutter insert to allow you to safely make dados using a Bosch Table Saw. It is bright red, making it easy to locate when you set it somewhere, and mine required no adjusting to make it flush with the saw table surface--it has four set screws to adjust the height. No one could beat Amazon's price of $9.74 and since I ordered it with the saw there were no taxes or shipping expenses. I ordered it on January 30, Amazon quoted a delivery by February 14, and I received it before February 10. This accessory works great and you really must have it if you are going to do any dado work with your Bosch saw.

Second one works fine

Well, the first one I received was bent -- laying it face down on the table top, it would rock considerably. If adjusted so the front and back edge were in line with the table, it was high in the center. I figured that would probably throw my cuts off, so I just shipped it back. Amazon had a flat replacement at my door a few hours after I managed to drop the old one in the mail. The replacement works great, and I'd probably rate it 4 stars if the first one hadn't been bent. Also, considering that the manual for the saw itself says very little about mounting a dado stack, it might be nice if the insert gave you some more info. I had to email Bosch tech support to get the secret for getting beyond 1/2".
