The parts and and delivery speed were ok, if a little expensive.
Cashback was declined for no reason. Upon raising a claim, it was declined again, stating the order had either been cancelled, returned or amended.
Don't bank on getting cashback and use an alternative company if they are cheaper. The cashback incident is enough for me to not recommend using them again. Any company that abuses Quidco in this way isn't a company I want to use.
