A spring is a spring right? Wrong! When UMI chose to manufacture our own line of springs we went all out. Designed in conjunction with a leading Sprint Cup chassis engineer, these springs are the best in the business. UMI’s springs are designed to add modern handling and a crisp ride while maintaining the factory muscle car appearance. Our front springs are wound from 5160 CrSi premium wire and feature a linear 530 lb/in rate. The linear rate provides consistent handling characteristics which are important for Auto-x and Pro-Tour applications while the increase in stiffness reduces body roll and prevents the “floating” feeling so common with the A-body. These springs are suitable for Auto-x and Pro-Tour applications as well as corner carving and general cruising. The ride height is engineered to be level with standard SBC, Pontiac 400 and aluminum head/intake Big Block Chevy as well as LS power (lightened cars may require spring trimming). The front springs are also suitable for full weight Big Block applications when ¼” nose down rake is desired. They have a tough, black powder coat finish and UMI proudly manufactures these premium quality springs in the USA.Shipping Notes

Worth it!
Color: Absolute Black, Size: Z1 Motor + Batteries
It works great! Makes a big difference and my coffee is better! Easy to use and clean. The stand is perfect to keep it accessible. Only thing I would warn customers is to pay attention to instructions on how to insert batteries.

High Quality and Surprisingly Powerful
Color: Absolute Black, Size: Z1 Motor + Batteries
The Pros:
Unexpected Power: I usually know exactly what to expect with the products I order, but this unit really blew me away. It is surprisingly powerful and handles everything much better than I anticipated.
Premium Batteries Included: It was a great surprise to find that it came with Duracell batteries. Seeing a name-brand battery included really speaks to the overall quality of the product and shows they aren't cutting corners.
Solid Build: From the moment I set it up, the unit felt sturdy and well-constructed. It is rare to be this genuinely pleased with a purchase right out of the box.
The Cons:
Operating Noise: Because the motor is so powerful, it does produce a bit more noise than some weaker units. It isn't a dealbreaker, but it is noticeable during extended use.
Bottom Line:
This is a high-quality product that exceeded my expectations in both performance and presentation. The fact that it comes ready to go with reliable batteries is a huge plus. I am very pleased with this purchase.

Pleasantly surprised.
Color: Absolute Black, Size: Z1 Motor + Batteries
Honestly, I bought this because it was on sale and I needed to add something to my cart to get one day free shipping. I had zero expectations and thought I'd use it when I travel and won't have access to my espresso machine but I'm blown away by what it can accomplish in its small form factor. It took 30s to froth the milk and it was well-incorporated into the milk, not with just foam on top and milk at the bottom. I could have the frothed milk all day. It's easier to clean than the steam wand and it does plant-based milk cold foam!! It blows the Ikea one out of the water for about the same price point. Glad I stumbled into it!

Works great for daily use, just be prepared to replace batteries
Color: Absolute Black, Size: Z1 Motor + Batteries
I use this every morning to mix protein powder into my coffee, and it works well. It is quick, easy to use, and does a great job blending everything smoothly without clumps.
For the price, it’s a great little tool and has definitely been worth it for daily use.
The only downside is that I do have to replace the batteries fairly often, about every 3–4 weeks with regular use.
Overall, it’s a very convenient and effective frother, especially for the cost. I would recommend it, just keep extra batteries on hand if you plan to use it daily.
