I also have another squeezing ball but I never touched it again since I've got this one. What I really like about this one is that after squeezing it needs about one second to go back to its original shape (doesn't mean that you have to wait till you can squeeze again). So you really have the feeling that you did something. (The other one that I have is like a bouncing ball and is round again as soon as you take the pressure away. That is annoying and not calming.)

So I orderd multiple different exercizers from the same manufaturer. I ordered 1 extra soft Eggsercizer (the egg shaped), 1 soft Eggsercizer, and 1 medium Eggsercizer, as well as 1 extra soft Theraband ball, 1 soft Theraband ball, and 1 medium Theraband ball. I have to say that out of all of them I prefer all of the Theraband balls to the Eggsercizers. The Eggsercizers are not as soft. The extra soft Eggsercizer is between the soft and medium Theraband balls in squishyness. I would say that if you want a really squishy ball start out with the extra soft or soft Theraband balls. The medium Theraband is much squishier than the medium Eggsercizer. The soft Eggsercizer seems equivalent to the medium Theraband ball. If you want something smaller go with the standard Theraband balls because they are smaller than the Eggsercizers.I am going to order more of the extra soft Therabands because I like how squishy they are. I bite my fingers and they help distract me from this destructive behavior. I carry one around everywhere and leave them all around my house. They are also just fun to play with :)

This product provides a number of benefits, for example; conveniently accessible in the house and easy to carry with you. Periodic use keeps my hand joints moving while increasing finger strength as well as palm muscle toning. This hand exerciser comes in a range of firmness to fit each person's needs. Applicable to physical individuals such as rock climbers and golfers to desk bound individuals in the very important need to maintain use of our hands. Decide what firmness you believe is appropriate for you and buy the one one level lower. You'll find that the less firm hand exerciser is more practical as you will be able to target the commonly less used ring and little fingers and still increase palm strength. Note: heating in microwave, as suggested, will adversely change material properties.

I have arthritus in a finger joints and this Firm (Blue) Standard Size ball works very well to therapeutically exercise the finger! If it get sticky, just follow the instructions to fix. HIGHLY RECOMMEND!!

Seriously, these Theraband balls are simply incredible! I have used a blue extra-large (pill-shaped) at work for two years now, and during this time I have squeezed it compulsively, mashed it against the desk, microwaved it, refrigerated it and even thrown it at people . . . and it shows no sign of giving up the ghost.It may seem a little expensive, but you are paying for some real quality. This is the ONLY EXERCISE BALL you should buy. You should get the extra large unless you have tiny elf hands.

I use it every 2 days during my work at office and I can feel an improvement of my "tennis elbow" problem.

This is fun to squeeze, and great exercise for the hand. I love how it feels - soft & squishy, but with resistance. I'm still having problems with my hands & fingers after a bad fall that resulted in a wrist fracture, and the development of RSD. This helps with strength, dexterity, and even nerve sensitivity.

I love these Theraband exercisers, which my hand therapist introduced me to. I've collected some of the toys I used in therapy to use at home. TheraBalls are small, comfortable, inexpensive and effective.They are great to use as "worry beads" but have had a fantastic effect on strengthening my poor injured and arthritic thumb.I left on behind after a visit, and the hostess didn't tell me, because she loved using it herself.Be sure to start with the incredibly squishy yellow one first and work your way up.Another great product to use with this is TheraPutty.
