The 90W, like other Glow Object ballasts, works extremely well. I have had no issues with the ballast and I am very pleased with it overall. I have used 2 of them, so far, to replace iron ballasts. If there was one suggestion I would make, I wish the wire terminals were screw contact vs the simple push / insert type. I have had no issues with the current terminal type but prefer terminals where positive locking can be made by tightening a screw. Overall, this is a great product!
