Query: Started Overheating within a month

I had a Vidal Sassoon hot air styler like this for about 15 years, didn't use it every day but really liked it. It started overheating, it would just shut off when half my hair was done. So I found this replacement, looks very similar. IT started overheating after only a month of use. I LOVE how this product works and would have gladly paid double for one that kept working longer. I find if I use the full setting it overheats within a minute. If I put it on low, it usually lasts through the entire styling, but since it's only on half power it takes me a lot longer. I WILL NOT buy another Vidal Sasson. I'll see what other brands are available, even if they cost more.
