We switched to the RM-VLZ620, we only get about 2 years daily use before the buttons start going bad. The RM-VLZ620 does not have the feature to learn all the buttons from another Sony remote, but I do not remember if the VL610 had it either. I know some of the earlier Sony models we owned did have that feature which was nice. The RM-VLZ620 is a little more difficult to "teach" buttons, needs good alkaline batteries for the learning process - and I have read some posts from people have purchased RM-VLZ620 that refuse to learn and needed to be replaced. However, of the 4 we purchased so far, all have work OK. I was looking for a new model but have not found any yet. Price seems to be about $30.00 US
