I like that it is easy for me as an old person with arthritis in my hands (and fingers) too use all of this stuff! It makes life easier when you have limited mobility or are not able to do some things yourself easily anymore due its age!! Some buttons can be hard if your finger isn't right behind them but overall good tool.
The only thing about visualon i dislike would probably just be because they don’t make any more products out there so maybe thats why theirs different then others? Maybe try one at store before buying online - otherwise great product. ! Good quality tools/equipment made by older generation people who understand how important these items really were back years ago. !!
