Hi all,

I'm looking to expand my ATC by adding more tool holder clips to my CNC. My spindle takes ISO20 ER20 tool holders, and I need to get more clips to hold the additional tools. Since the ones I have now came with the machine, I looked into the price of them individually and have to admit I was quite shocked, with ones like these from Laguna coming in at $45 each: https://www.shop.lagunatools.com/ISO...-Holder-Clip_2

I'm not against paying for quality, but I like to understand why. There's no details in the product description that help me to really understand what justifies it costing so much. My best guesses are resistance to heat and fatigue and overall precision in their construction, but is there more than that? I'm comparing them to others like this:
- HOZLY ISO20 Tool Holders ($9 each) (https://www.amazon.ca/HOZLY-ISO20-Ho.../dp/B0B1PMJLFZ)
- RED's ($6 USD each) (https://www.ebay.com/itm/35464071314...mis&media=COPY)
- Various others on Alibaba that range in price from $10 to $25 each

Would you spend the full price for the brand name ones, or are these other OK?
