Description:

The HS1-HDR4 kit by ACT features their most popular Heavy Duty pressure plate, designed to increase clamp load, reduce deflection, and maximize clutch life through an exclusive diaphragm design. Each diaphragm undergoes a four-stage heat-treating process for exceptional performance. Precision cover stampings ensure rigidity and consistency in the pressure plate. The kit includes a 4-pad rigid race disc crafted with high-quality ceramic friction materials. The chrome-moly hub is heat-treated to ensure strength and durability. The lightweight, rigid design facilitates quicker shifts and provides smooth, trouble-free service. Although engagement with the 4-pad rigid race disc is harsher, shifting is faster. This kit is well-suited for smaller disc sizes in smaller engines.

Comfortable Shoes Right Out of the Box
Size: 9, Color: Black
I bought these shoes for my husband. He has a very hard time finding quality, comfortable shoes. These shoes are just as comfortable as his New Balance. He uses them as a dress shoe and wears them at least once a week. There was no break in period necessary. They were comfortable right out of the box! The only thing we didn't like was the white sole color. Once I knew he was going to keep them, I used a black sharpie marker to color the soles black. Instant amazing, comfortable dress shoes. They were well worth the cost. If you or your SO needs a comfortable pair of shoes, we highly recommend them.

Paid for new, received used.
Size: 9.5 Wide, Color: Cognac, Size: 9.5 Wide, Color: Cognac
Arrived dirty as if someone whore it for more than a few days. Maybe I was mistaken, but I saw nothing about “previously used” on the Amazon page. Returned it. I would suggest that the company use quality control when it comes to shipping. The shoes seem find otherwise. I ordered 9.5 and it was just a bit tight. If I reorder I will go for size 10.

Decent Shoes with Misleading Description (Not Leather)
Size: 12 Wide, Color: Black, Size: 12 Wide, Color: Black
I only look for leather when I’m purchasing dress shoes. Under the description “details” on this item it lists the shoe as leather upper and inner lining. A photo shows “genuine Napa leather lining”. If you keep reading (which I have now that I’ve received the shoes) it shows “faux leather” in the small print and that is not “leather”. I run a small leather business and this irks me because it’s clearly false advertising. The details also show the product is made in Brazil but when they arrived today, the shoe tag shows “Made in China” and “Man Made upper and lower”. I don’t hate the shoes. They look nice. What I know is they won’t hold up over time like leather, which is why the description should be accurate and not misleading.

4 USB-C ports, Quality Build, Value for non-KVM Users
Style: 8-in-1
If you’re looking at this product, it probably means you are curious if this is better than the cheaper generic brand hubs and don’t really want/need a full KVM. It most definitely is, premium quality, has external power for powering any type of higher power draw usb device you may be using. The thing that sold me was that this was the cheapest non kvm hub with 4 USB-C ports (instead of 2 or 3) in addition to all the extra USB-A ports it has. I thought about going the USB-C pcie expansion card route but truthfully I do have one or two usb devices that have always had weird behavior on just motherboard power, and shocker I know right, no issues on my externally powered hub/splitter, total game changer. Do yourself a favor and eliminate the hastle and buy the brand you can trust won’t end up being junk that you want to send back!
