I know there are multiple threads on the subject of battery tenders. I wanted to solicit opinions on this deal. I have Ryder insurance and received this offer from them. I wanted to get a battery tender and this one looks pretty solid.

The CTEK MXS 5.0 (Part No. 40-206) Battery Charger is a fully automatic, microprocessor controlled charger with a built-in temperature sensor and a unique combination of advanced charging modes. It is the most effective and versatile consumer charger ever made by CTEK. Alligator Clamps and Eyelets included. The MXS 5.0 is suitable for cars, trucks, motorcycles and snowmobiles. It is delivered with a 5-year warranty.
The retail price of the charger is $89.99 (best price on Amazon $68). Now available exclusively to Rider Customers for $59.99 (33% discount)!

Any opinions? Thanks in advance.
Jim
