30pc Universal Diamond Burr Set Rotary Tools 40 Grit

There's nothing wrong with the dimon impregnated bits that I ordered they're as advertized and what I expected and needed. The delivery was prompt as well - five star. However, instead of receiving two sets starting with the smallest diameter and another set of the next size up in diameter like I thought I was ordering I receiver both set's in the same diameter. I have to say the mistake may have of my own doing. After putting the first item in my shopping cart I intended to scroll down to the next size up and click to place it too in my shopping cart but it't never that simple - after clicking the first item into my cart the the webpage I was shopping automaticlly switches me to some new page taking it for granted that I was done shopping the page I was on. After the tedium of finding my way back to the page I wanted to continue shopping I suppose it's likely I inadvertently chose the same idem rather than the next size up. The product deserves five stars - the website get only three stars for giving me the runaround.
