Getting really annoyed with these hpt!!😒

Everyone says blue dye is bad; get a frer. Okay. 
Then everyone says frer (curved) are horrible too. 
Both of these are all that's sold where I live! What the heck am I supposed to do then?!😔😡
(Yes there's the Walmart or dollar store cheapies, but I want to use a good brand. Is that too much to ask for?)Â
