I guess I'll have to send him back, however, because this ball so strong report by adhesive / Uhu / solvents that even my two roommates to complain about (Mind you, who sit in different rooms ..)
I wait two more days and then reports to you - buy recommendation there is anyway no such products should generally not available, price & optics or not.
Addendum:
Out of laziness keep .. ball stinks 6-8 weeks and the first 5 of them (very!) Strong, then it declines ..
A friend bought a ball of Togu .. The smells new less than my ball now report (and there is almost nothing) .. Just as a well-intentioned tip;)
