At first sight I thought these therabands looked flimsy. I was wrong, they are made of a dense, highly elastic polymer. I bought the 15 lbs resistance band b/c I already use a grip strengthener. The 15 lbs resistance is almost more than I should've started with so, if you have weak wrists/stabilizer muscles I would start with the 10 lbs resistance or maybe even the 6 lbs. I take Gracie Jiu-Jitsu and grip strength is important so I bought the captians of crush hand gripper - which are great - but they only account for flexor work, theraband has a multiplicity of exercises. Here are some pros and cons:Pros:1) The bands are made of high elastic polymers2) They are easy to grip3) Easy to transport anywhere4) They target all areas of the hands, wrist, forearms, shoulders and even the thumbs!5) They do provide relief from tendonitis (tennis elbow)6) Include exercises in tensor, flexor, flexion, extension, abduction etc.7) Provide resistance in both directions.8) They target the small flexor muscles that traditional free weights cannot9) They provide dynamic resistance10) Well worth the priceCons:1) They could come with an instructional video b/c some of the exercises are hard to understand2) They could include - with each exercise - a description of what muscle group is targeted and how it can benefit the user i.e. relieves tendonitis, increase stability in the wrists, etc.Bottom Line:I would recommend this product to any one with or without therapy needs. Theraband boasts that it relieves tendonitis in the elbows but it also includes exercises to reduce it in the shoulders as well. Wrestlers, grapplers, swimmers, boxers, mma practitioners, baseball players, football players, tennis players, hockey players, lacrosse players and your average joe/jane will benefit - with proper use - from this product. I suggest you find exercises that benefit you and stick to a regular routine with proper nutrition for the highest level of benefits.
