Cash crusaders Dixon worst product ever

I was looking for an secondhand angle grinder at cash crusaders princess crossing, they didn’t had stock so I told the salesman don’t worry I will by a new one at pick and pay then he told me that they have also got new angle grinders Dixon so I bought the 900w angle grinder WORST MISTAKE ever it didn’t even last 5 months and it’s giving problems. My ryobi Handline grinder worked harder then the 900w Dixon and lasted more than 2 years . So I took it back today , they’ve told me they have to book it in for repairs and it’s going take 21 days for repairs, so I must sit for 21 days without a grinder , Dixon is the the worst product ever , that cheap checkers hyper grinders that they are selling is better quality than DIXON . I’ve waited 45 minutes for the manager . If you want my advice don’t by Dixon
