Review title is I mean they're ok... [SEP] So, I bought this set because I had a very big project that could only get cleaned by using a product like these. The project was to clean all this nasty glue and dirt off of the floor pictured in the included images. There is a before and after image for those who want to know how much I asked of this product. And while the razors themselves are very good quality and last a decent amount of time per razor the actual razor holder is what I ran into major problems with even when I bought a more professional one at my local hardware store. Now while my project was unique I would have to personally say that if you have something less intensive than what I did you should not really run into many problems. I completed the clean by cleaning the tool and razor after each and every tile that was scraped making sure that no moisture stayed on the device or blade as that is what mainly cause the issues however I did have to eventually go out and buy a more rugged blade holder as the mechanical part to remove the blades and to slide the blade in and out of it malfunctioned quite often and eventually both broke.. only 1 razor blade actually ever broke which means that I still think that getting so many decent blades at this price made it worth it even though the tools broke. I hope that these images and my experience can help any potential customers to know about benefits and problems of this product and again I would overall recommend it.
