Query: Not for me,

I loved Fellowes original trackball - Thumbelina. It fit my small hand well and was a joy to use. particularly the 'lock and drag' feature.Unfortunately, the present trackball is awkward to hold and use. It lacks the lock and drag feature that I as a writer enjoyed so much.Regretfully, I cannot recommend this trackball to anyone.
