Product review (1 stars): cheap plastic may easily break.
It broke quickly.  The plastic design is flawed in general.  This part looks like it costs 50 cents.  Not buying one isn't an option, but I would prefer paying double for higher quality option.

edit - i'veniw purchased 2 of these and both broke shortly thereafter.  Again, happy to pay more fir a higher quality option.  I will now yse the shell and fabricate my own.

DO NOT WASTE YOUR MONEY!
