The product is good, but delivery time is absolutely not corresponding to seller promise: 43 days instead of 8 promised. Seller take a payment for EMS, but sent with cheaper ePacket. The product arrived with a month delay!!! The seller is not answering noting except of:"Order sent!!!"
In other words - buy the same product in other store.
The seller is responsible, the order came quickly, about two weeks before Magnitogorsk. In the case I tried, the Kants saw tolerably. To quickly correct the edges for the House will go. Plastic pour cracks not used yet
