50/50
Corsair
UPS
Will only support these companies if there's no other alternative. Fortunately there's always an alternative.
Corsair products, with one exception, have been stellar in compatibility, performance and quality across their entire line of products. The one exception, I received top notch service, free return shipping and replacement of the prematurely defunct item. Actually, Corsair sent me one level higher in their product line and 50W more power with a higher 80+ rating for my troubles.
The original was still available, as it was from a newer model line also. It's hard to put them down for service that good!
UPS - U P - Slow - the reason they are so slow? They have to make sure they take the time to plan out the damage to every package just right before they deliver it. **True story...no really! I saw it with my own 20/20 vision. Picking up a package at the local terminal I missed them delivering, I could see the trucks backed up to a large conveyor. I stood there watching UPS package handlers/truck un/loaders, literally (That means for real!) tossing the packages out of the trucks, almost always bypassing the EZ-Roll ramps to the conveyor belt completely. What caught my eye were the several DELL boxes plainly stating FRAGILE/MONITOR/COMPUTER PRODUCT/HANDLE WITH CARE/DO NOT THROW, DROP, EXPOSE TO MOISTURE, printed on them clearly in bold large black lettering, come flying out the back of a couple trucks, hit the end of the EZ-ROLL and flip end for end several times as they moved down the conveyor! I asked the clerk attending me if the guys back there were playing football and who was winning? He turned, quickly dropped the blind and closed the slats and with attitude said, "We DO NOT play football with packages!" A few years later, supervising at a warehouse, I had a customer-important damaged package with missing content (broken open). The UPS rep came in that afternoon and refused to pay a claim because we had cut the tape on the package. We did so to get a count, this was an important customer and the order was time sensitive. The rep said since we opened the box and touched the contents they wouldn't pay the claim. Btw...It is in their policy to inspect damage and contents WITHOUT their rep present. He claimed we could have dropped the box and cause the break losing the parts. Is that nerve or what?! I asked him who won the football game played with the package and he got so mad he raised his voice saying, " We DO NOT "fourletterwordendingwithINGhere" play football with customer packages!" and walked out. I reported him. He was fired, as I had witnesses, but UPS still wouldn't pay giving no good reason. I strongly dislike U P - Slow!
