The ROP Shop chains are an adequate middle-ground option. While the construction isn't as robust as professional-grade chains, they provide sufficient bite for a standard residential driveway. I noticed some slight rusting after the first month, so I'd advise drying them off or spraying with a bit of lubricant after use.

Idk man, I shoulda just spent the extra 20 bucks on better shoes. These things are already making a weird dusting sound after only a month and the stopping power feels kinda spongy compared to what I'm used to. They fit okay I guess but I wouldnt buy them again for my Versa. Better off looking at other brands tbh.

Way too expensive for what you get. One of the tabs snapped while I was assembling it and now it sits crooked. I expected better quality for this price.

Honestly this is the best brush I've ever used for liquid foundation. It doesnt soak up all the product like my beauty blender does and the finish is actually airbrushed. Its super soft on the skin too which is a plus because my skin is sensitive. Expensive af but worth it if you want that glowy look.
