Query: THE BEST

When I noticed that I was gradually losing strength in my grip, I began my search for a hand exerciser. I'm sad to admit that I went through a number of them that I was disappointed with. A couple models I bought hurt my hands and one of them even broke. A lot of wasted money. Then I located this one on Amazon (I chose the blue one). Perfection! I love that it's so comfortable to use and that it exercises each finger individually - and each finger gets an equal workout - unlike the old V-style exercisers. My grip strength showed improvement in one week! I don't even use this every day anymore, but I enjoy picking it up and playing with it here and there. Today my hands are noticeably stronger and the product looks like it will last a long time. Highly recommend.
