Review on Wirefy 200 Heat Shrink Tubing by Kaveen Reyes

Well done seller - served quickly. However, the product failed quality control. All black pieces were slightly smaller than their red counterparts. I used to use pieces of shrink wrap to install sound systems and I know 3/8 of the pieces fit banana plugs. These red pieces fit perfectly as expected. However, the black parts were too small to fit on the banana plugs. I then looked through the entire box and saw that all of the black pieces were smaller than their red counterparts. To get the job done I used 1/2 parts but there are less than 3/8.
