I ordered twice from stone stream. When I ordered 2 years ago, it was an older model, today they are selling a different model. I am using an electric shower so make sure to choose the right model if you buy it from them.
1) Delivery duration was about a week
2) Product is as described, will soften the water and I did feel some increase to my water flow. Smaller holes make it stronger I believe.
3) I got a value kit, and they send a hose and replacement filters in the box as well.
Will buy again in the future.
