Good product
Size: 2.5", Style: Closed Hooks
Strong magnets that stay on wall once applied. Definitely holds the weight that it says it holds on the product. Good size to hold my halters in my barn. Would buy again and I think the price was a little high for this product, but it was worth the purchase.

Versatile and Sturdy Storage Solution
Size: 2.5" & 4" - 4 Pack, Style: Open Hooks, Size: 2.5" & 4" - 4 Pack, Style: Open Hooks
The GATOR MAGNETICS Open Storage Hook has been a great (pricey) solution for adding hooks that are strong and useful. Its simple yet robust design makes it incredibly versatile for various uses around the house.
The hook feels sturdy and durable, capable of holding a surprising amount of weight without bending or warping. Installation is as easy as blinking your eyes; the really strong magnets allow for easy attachment to any magnetic surface, and the hook remains securely in place.
I've used it for hanging lights and bags in my office and bedroom, providing a neat and accessible storage solution in any setting.
The open design ensures quick access to items without the hassle of removing them from a closed loop, which is a fantastic convenience. The magnet seems to be protected well enough with a rubber surface so that I don't have to worry about damaging my tables that I have attached these hooks.
In terms of value for money, this storage hook is pricey but no competition that I've seen with the same level of durability and convenience. I'm impressed by its performance and versatility, making it a must-have for anyone looking to organize their space efficiently.
Pros:
Sturdy and durable build quality
Easy magnetic installation on metal surfaces
Versatile usage for multiple items
Convenient open design for quick access
Doesn't damage surfaces
Cons:
None that I've encountered so far! (Maybe price?)
Overall, I highly recommend the GATOR MAGNETICS Open Storage Hook for its durability, versatility, and exceptional functionality. It's a small investment that brings significant organization and efficiency to any space.

Amazingly strong and versatile
Size: 2.5" & 4" - 4 Pack, Style: Open Hooks
I saw these advertised on Instagram and immediately purchased a 4 pack. I really wanted them to work but after trying them on 4-5 different steel surfaces I couldn't'[t get any of them to stick well or hold anything heavier than a wet towel. Maybe a bad batch? A shame.
The company took the time to reach out to me after seeing my first review where the hooks wound stick to metal poles in my studio. I definitely was not expecting them to reach out to address my issues with the hooks I purchased and returned. After trying the new replacement hooks out I now could not be more impressed! They are strong, well made and easy to use. The hooks and the magnetic baskets are phenomenal and I highly recommend them. I did a test with the hooks, which held a 75 lb weight with no issues on the side of a craftsman tool box! It seems that any early product issues are fixed. The customer service is fantastic and they really took the time to address the issues and keep their customers coming back happy. Well done! Gator Magnetics is definitely a class act in my book!
