Lo uso constantemente y ya no consibo mi trabajo sin este producto , ojo , es para personas que trabajen los azulejos a plomo y nivel .ExelentBest price I could find, Make sure you buy a pack with the tool and wedges.I’m so glad I made the purchase. The floor is perfect and when it’s time to remove just kick them!The quality was very good. I used the 1/8" clips and they worked fine with raimondi wedges. Some don't break off clean but for the prices I can deal with that. Shipping is fast and I just bought my 2nd batch of 800These work just as well as the name brand ones. If you don’t need to buy 2000 of them then certainly buy these but since the biggest size they have is 800pcs, it would cost just a bit more to buy the Raimondi clips when getting 2000.The clips seemed like a nice idea but they had several problems (I assume all of these types of leveling systems have the same problems). When tightened, the clips were often in the way of thinset that was pushed up in between the tiles. It was pain staking to remove the dried thinset from in between the tiles after the clips were removed the next day. When tightened the tile was not always level. After drying, the upper part of the clips did not come off very quickly or easily. Several of the them broke and left small pieces of plastic wedged between the tile making my job harder. Not only were these clips hard to use but they did not do their job very well. I recommend using the cheap white rubber spacers that are reusable and less rigid.Great product, love this system.The clear clips are by far the best! The red ones are crap. I've used over 2000 of these. The 800 pieces will do around 500 sq ft.they work well
