I can see this being useful for adjusting the spine of a small child
Be warned. This is NOT VERY strong at all. I can see this being useful for adjusting the spine of a small child. I bought this for myself and I sit 8 hours a day and my lower lumber region is quite stiff and hard to crack / adjust. Using this device on my lower spine had little effect.<br /><br />It's disappointing it costed so much for a device so simple...
