Conclusion: We bought this model for our home in Puerto Vallarta in 2006. The outside rubber coating is now melting and impossible to hold without getting black goo on your hands. Because of the price and quality of this unit we have always kept them in a secure and protected location. We saw a little of deterioration last year-2010, but this has morphed into total disaster this year. We were very happy for the first 4 years--not now--would not recommend.
