Philips Norelco Replacement Screen and Cutter fits BG2020

I have replaced the head at least 4-5 times and the head keeps falling off the machine while shaving. I cut myself several times too because of this. The design is flawed. Why can't the machine hold the head? Perhaps, a button to release the head instead of just pulling it off would have helped the design. I am looking for other products.

I ordered this for my Bodygroom 2020. The foil itself worked fine, but for some reason it didn't fit as well into the handle as the original foil did. It was too loose and eventually fell out on the floor while I was shaving. This made it even more loose, and when I tried shaving with it again, it fell out again, until it eventually stopped working. It's possible that the foil was defective.

Why would retailers sell an electronic grooming device that doesn't sell the replacement blades? Yep! I had to search the net for replacement blades for a $60.00 men's groomer that is being sold at Target, Walmart, Bed Bath and Beyond and probably others, but don't sell the replacement blades... Go figure.
