good wire

### ⭐⭐⭐⭐⭐ 







  
  
    Great wire
  

*by J***. on Reviewed in the United States on May 29, 2017*

For me personally this wire has worked perfectly. But it is very difficult to see when making claptons and fused claptons etc. So if your eyesight isn't really great you may need either a magnifier or just a bigger gauge of wire. Probably 36g or maybe even 38g.

### ⭐⭐ 







  
  
    Didn’t get flat wire, got round wire
  

*by C***Y on Reviewed in the United States on May 18, 2018*

So order ribbon wire and got 40g round. Don’t know if it was just a mix up or what but now I have a spell of wire I didn’t order. Not worth returning but still didn’t want 40g round
