Depends I guess. Maybe my spike are less resistant and the Braun one are better.So, you think the advice about spikes should be revised, in favour of your approach, or not?
Is it just about durability + cost
Cost is more or less the same, maybe spike cost even less depends how much they last.
Let's assume one spike cost you 3$
One filtered needle is 0.50c so 6 needles cost the same as 1 spike.
After 6 draws the spike has one and it's costing less.
Thing is if you need to draw different substances in the same syringe the spike is a pain in the ass, the needle win 10 to 1.
Both are fantastic options and one or the other should be used.
Aesthetically spike are horrible.
