These knobs are excellent. They are weighty and comfortable, feel good to turn. I've put them onto my stratocaster clone that I've been building, and they fit perfectly. I really like them. They turn smoothly on my guitar and look excellent, the metallic feel is very premium despite the cheap price of these knobs. I would purchase again for any replacement knobs I might need. They also did come with the small allen key to tighten the knob onto the pot, rather than having to search for my own. I did have to try a few times to ensure that they were on correctly and not a slight angle, which was a bit difficult at first, however that was overcome easily and did not distract from my experience with the product, as now they are on I do not have to touch them again. Again, these are definitely worth the purchase if you just want something simple and plain to accentuate a nice guitar body paint, such as my white body strat. I personally prefer the tall knobs such as these rather than alternatives such as speed knobs, and definitely more than other more flashy options. They work well and again, are worth the purchase. 5/5 stars
