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

I was always an Ernie ball fan although I tried a lot of brands in the past. A friend of mine was using DR’s he suggested me to try these babies.
Well I have to say I was blown away with the sound of these strings, the clarity even with mushier distortion tones was unbelievable. My guitar was sounded warmer with more harmonic overtones jumping out in every chord and greater string definition when soloing.
My only complaint is the price as these babies are way more expensive than the Ernie ball, so 5 sets of DR’s cost like 6 sets of EB’s.
Personally now I use both brands EB’s for rehearsing and bedroom play, DR’s for recording.

The Pure Blues from DR are superb hand made strings, perfect on Strats but also great on humbucker style guitars. They give a particular warm tone on those alnico vintage single coils, especially on the neck pickup, while reacting to the picking well enough to transfer much of the attack to the coils, creating the effect of a slightly compressed sound where you can hear each string you play clearly. They take gain well, however those are not recommended for metal tones. They are fantastic for blue and rock. Pay attention to the printed instructions when changing the strings, they do break as the manual suggest. While you will still want to change the strings often, the DR seem to last forever and keep both tone and tune longer than many other strings I have tried.
