I've been a guitarist for 16+ years. I've been using these strings for the last 4 years. I absolutely love them. I mostly play metal, some blues and rock. I don't know about other people saying they go flat after a week. I've used these strings on my Kelly for a month or more at a time. With any string, you should always wipe down your strings, neck and bridge to get rid of the sweat from your hands. I always use fret ease before I play to clean them. They sound very bright and have great sustain. I can whammy all day and never had one break on me. Even when I change them they are still "OK" but like any other string, after some time (about a month of everyday playing) they need changed. Only strings I use.

I've used Blue Steel strings for about a year and a half and had absolutely no problems. The tone is great, and I can really dig in. I haven't had one break like other strings.

These start out sounding amazing but that only lasts for about a week and they go downhill fast. Once the week passes they are flat, the G gets buzzy suddenly, generally stale sounding.

If you only need a set of strings for one maybe two gigs, these do sound pretty awesome - but I don't think the DM 1973 RI's are that bad comparatively.

Compared to the original Dean Markleys, there is no contest. The original Dean Markleys, in my opinion are terrible strings; but the Blue Steel line is one of my top favorite strings. They last long, stay in tune, and sound great. No problems here.

I had these strings for a long time. So I switched to d'addario for a while and what a big mistake that was, blue steel is the best strings I have ever used. Do not buy any other guitar string except for blues steel, its amazing in tone and quality.
