Workable, but quite evident that they are not a real well-made product. Challenging to install underneath cabinets because of awkward position required. Use of three batteries seems it should make them last, and of course the amount of use will wear out the batteries, but - if used moderately or less, one would think the batteries should last longer. It is evident that continued use will require frequent changing of batteries. The quality of the products are not equal, that is to say that the lighting on one is not as good as the two others. Overall the product merits just an "OK", or "Fair".
