TamsPalm has done a review of BoxWave “Slim Rubberized Shell Case” for Treo 680. "Protective cases for mobile devices usually are made out of leather, metal or silicone - with an oddball sleeve(darn cool) or two thrown in for kicks. Boxwave’s latest creation is completely different. It essentially consists of a slim PVC shell that goes right around the Treo…and changes its color in the process. This time, Boxwave shipped the case in a cardboard box - in the past, products arrived in envelopes(unharmed). Anyways, no transport damages…no issues here(except that some postal services do not deliver parcels to a mail box and send a postman instead, which usually comes when you aren’t at home…)."
