No , not for that reason ..😁
..from shaking with wits out of paint bottles to mix them up, esp if they are a bit older .
I bought one of these Timodel Shakers a year ago , was a bit dubious how effective it would be , as it is a rebranded generic chinese nail polish shaker. However after using it for a while I can report it works well . With new paint if you added some thinner to the bottle @ 15 seconds and your good to go. Also works for rejunvinating older paints that have settled. For ancient paints I give them quick stir to break up the sediment and then shake them for 30 seconds , with good results. I work mainly with Tamiya, Alclad and Vallejo FYI
This one is battery powered ( not great) but works far better on a mains lead . Comes with a UK plug too . Paid £28 for mine from Jadlam , they are on eBay for the same.
I've no relation or stake in the company , just a surprised happy user .
