Product review (5 stars): Good construction and higher quality materials.
This is my second coil assembly. The first one was not this clean and well designed as the first. The coils are evenly spaced and made of higher grade material and a thicker gauge. The coil spacing was even through the bends. My last once had the coils bunching and eventually touching and shorting in the bends causing them to short and weld together.
The picture is as delivered.
