I can't fault the delivery speed and the customer service to some levels however: 1) The reviews logo on the site doesn't link to here and instead to a page with their own curated reviews. 2) The film did have slight damage to it but I thought It'd be fine. I would say my DIY level is above average and the windows were triple cleaned (Once with pressurewasher a week before, once with soap and washing up liquid a few days before and once with the "tint slime" on day of application). However it creased really easily and didn't seem to come out with the heatgun. 3) The only instructions on the sites are videos that make the job look really easy and simple cut down to 3 minutes. I would have been interested to have seen even their professional do it on a full video to see how much time it would actually take. The paper instructions were much more detailed but recommended I'd need to remove multiple bits of trim in my car. If I knew this I wouldn't have ordered. So overall I failed doing it and wasted £40. Was this because I'm not experienced enough? I'm not sure, but then if it's where you're good enough at doing it every time first try then I doubt you'd buy pre cut windows and instead buy rolls and cut it yourself. Just going to pay a professional to do it themselves which isn't a lot more expensive in terms that it could be another 2-3 attempts at DIY before perfecting it.
