The cutter was sharp and cut the tubing just fine. The diversity of the connectors were great. The tubing seems great quality. No leaks when connecting to RO system. ### ⭐⭐⭐⭐⭐ Review *by N***N on 3 February 2025* SIze is as stated. Installed without issues. ### ⭐⭐⭐⭐⭐ Review *by C***N on 28 January 2024* TLDR: 🌟🌟🌟🌟🌟 This kit provided the ideal solution for my under-sink water heater installation, with a great selection of fittings and ample tubing. I was in the midst of setting up an under-sink water heater and faced the challenge of integrating it with my existing water line to the refrigerator, which had a smaller-than-usual 1/4" tube. My initial attempts to install a tee in the line were unsuccessful, resulting in leaks despite trying different fittings twice. Then I found this kit, which turned out to be exactly what I needed. It came with a comprehensive assortment of fittings, making it much easier to find the right parts for my setup. Additionally, the kit included plenty of tubing, which was a huge relief. A crucial tip I learned from this experience is to avoid using clear 1/4" tubing as a substitute. It's likely to cause leaks and can jeopardize the whole installation. This kit, on the other hand, provided reliable materials that ensured a secure and leak-free setup. Overall, I'm extremely satisfied with this kit. It effectively resolved my installation challenges and made the process of setting up my under-sink water heater much smoother. ## Frequently Bought Together - ESHIONG NSF Certified 3/8" O.D.
