I think you will find B-D's are better quality but thats just my honest opinion. I used Teurmo's for yr just switched got lots of advantages with B-D's.
Getpinz is a good place also!
never will I bad mouth X-Biker he's a good dude!
notice the B-D's are bigger and sturdier and can draw at least 4 cc's back. I like the bigger grip on top both are 3 cc syringes, the bigger is the B-D the small Teurmo's.
The bigger plastic top helps when you have big fat fingers and doing on-sites to grip better.
Most all hospitals use B-D's also if that means anything.
Teurmo's the top one B-D is bottom both 3cc syringe.
Terumo claims to have a thinner barrel, but then again, so does B-D. The only difference i can see is what DG pointed out, it holds more fluid, plus bigger top, for easier handling. its personal preference, i wouldnt be surprised if i didnt feel a difference in the two
