I ordered this a while ago not expecting much, but I have been very positively surprised. First, installation was a breeze and there were no problems fitting it to my 10+ years old toilet seat. No leaks so far and all parts are of high quality. Of course the best part is using this product...  I don't know how they have done, it , but the flow and the aiming is dead-on... I did not have to adjust my seating habits at all, but the SlimEdge Bidet did it exactly right on first try. I highly recommend this product for folks who are looking for a simple and reasonably priced and at the same time quite effective bidet solution for their older toilet seats.
