DR Strings Pure Blues PHR-10

Take this with a grain of salt while I am talking about set I've got. Not going to return them or ask refund I have just junked them. Your set might be perfect but I am not getting 10 sets to test them out just to form my opinion.
I've got this product for my new Tele. Tele came with 9's and it was feeling to soft.

By stringing the Tele with this strings E1 felt strange. I've felt some unevenness on E1. Like ribs on the surface. B and G strings felt normal.
During stretching E1 broke. It broke by the end ball . Sure it might be normal place to brake in some guitars but this was in Tele.
I Could not even find original ball end so I have taken one from the string that came with Tele. I've twisted end of a string around that ball and soldered twisted part so id can't unwind. Re stringed E1 again.
Stretched it and start playing it. First bend and it broke again. This time just above bridge pickup. It did not touch anything.

Positive:
Sound was kind of dark. Way darker than strings that came with the Tele. This is not bad considering that Telecasters can be to bright. So I guess this strings if they pass QC might be good for Fender single coil vintage alike guitar tones.

Negatives:

Broke twice before giving me a minute of play time. Broke on different places to. So no Idea why.
Ruff feeling on E1 but I bet that that comes from string being faulty.

This strings might be good for someone but I am not getting them and not recommending them to anyone I know.

I went back to guitar once more and I've checked saddles and nut and what ever I could. Everything is smooth and there is no reason for this strings to brake. Not on the guitar.

I've re stringed the Tele back then with other brands tens and even now they are sounding good and have not changed a bit.

There fore I can't recommend DR string to anyone. Sorry
