Summary: It gets the job done, but isn't very current. I live near an AF base and they are building a lot of new subdivisions. None of them show up in my gps. Need to work on keeping maps updated better.
335T is great but updating maps each year costs about the same as the GPS itself. Suggest you buy a model with Lifetime Maps

Summary: If you expect only to use this for a short period of time, it is great. However, with annual updates for maps costing about what the GPS itself cost, I cannot give this a higher than 3 rating. Having never had a GPS before, I expected that "LIFETIME" included maps. for the 335T, it does not.
Summary: Very accurate and hasn't lead me the wrong way yet. Maps are detailed enough to track very rural locations even on wildlife management access roads. However, the battery life is terrible in my opinion. You'll always have to have a plug nearby.
