Quoted from dsuperbee:You didn't miss anything with the WW glass. The translites looked much better and clearer than the glass. I passed on one after seeing it in person.
dsuperbee is correct on the CPR WW BG. A friend of mine actually sent his WW BG back for a refund to CPR. However I must say, CPR did an excellent job on the ES BG. I bought one and very happy with it!!
