Destructiontools review for EUR Tax Dual Price B2B Europe

I installed this app some time ago to shop the price off my products with and without VAT. Yesterday I noticed that the price for some reason wasn't visible anymore. After some debugging I noticed that this was because off the app, the only way to keep it working was to activate the app by paying the monthly fee. Since I noticed this myself, who knows how long the prices weren't visible anymore on my webshop and how many sales I probably have lost because of this. After uninstalling the app, the prices still weren't visible. The installation of this app messed up the code of my product page, I had to manually put back all the code before my prices are available again.. Never install this app!!
