Additional Time and Fees
Paying for customs fees after paying for shipping on the website was not expected. The product was held up in customs for additional days because they didn’t know what it was. I had to take time to provide product information.

I live in Poland (but I'm French)
I live in Poland (but I'm French). I drove from Poland to Bulgaria, and the problem was that I noticed my car was using coolant and losing power. I took it to a garage, but they couldn't find the leak and just replaced a part related to the spark plugs. However, I still had the same problem. So, I ordered the NO LEAKY cylinder head repair product and was able to drive back to Poland without any further issues (1300 km). So far, everything is still fine.

A real scammer
A real scammer, I haven't been reimbursed since March even though the order was returned without me receiving it. For months, customer service has refused to reimburse me even though they have all the proof. Run away, keep your money.

Very poor customer service
I can’t comment on the efficacy of the windscreen repair product I ordered as it arrived without the curing film and blades which are apparently, required to use it. Having contacted the company several times and been told that they were looking into it, I requested a refund. Again, they have been ´looking into this’ for a month. I am not wasting any more time on this company and cannot recommend them at all.
