Kamoer KCP PRO2 40-210ml/min high flow peristaltic pump 12V dc variable speed small dosing pump for lab chemical experiment with Norprene tube 3.2mm ID× 6.4mm OD and power adapter

I bought this to make a diy fertilizer dosing system for my planted aquarium. The minimum flow rate is as stated about 40ml/min. It seems reliable and works nicely. The tubing that gets squashed by rollers to move fluid (the definition of a peristaltic pump) will eventually wear out but it usually lasts a long time we use these type in my research lab. So this product is good especially for the price. I don’t think this type of pump is advised for continual use however. Best for intermittent applications

I like the metal construction, the visibility of the pump working, and flow rate of this pump. Purchased to dose chlorine into my above ground pool. Automated with Kasa smart plug, this pump will dispense 32oz in 12 min on low speed setting. Longevity is unclear at this point given time in operation, but am very happy so far. Good quality, good value

Item broke after one use. We purchased this as a back up and when we needed it it broke first time. Unfortunately it was one week after the warranty so we got to throw away a new pump. Do not purchase this item

I'm using this in a fertigation system that I built. Since I am pushing liquid against a small pressure in the sprinkler system, the 1/8" tube fittings were not tight enough to hold. I replaced them with 3/16" fittings. The system works with this setup.

Would have given 5 stars if power source worked I didn’t bother to return it because I had another power source so I can’t comment on the return policy but the pump works great

using to top off a reef tank kalk reactor by avast marine. Tank has never been more stable, way better than using ATO.

Very happy with that, it works great. You can set the speed. Way cheaper than any other products I saw.

I have had this running at an extremely low 2.1 ml per minute for a few months and it’s been running silently without issue.I like the ability to adjust to a tenth of a ml.
