Ok, but measure your flow rate! By Greg on 10/6/2017

Works great, but runs at 1.8 mL / minute, not the advertised 1.1 m/L. Be sure to calibrate each one you buy -- both of mine were different, and neither were the advertised 1.1 mL (1.8 and 1.7 for the two I bought.)

Best Inexpensive Way to Dose By Tom on 9/3/2017

I have 3 of these dosers. I've been dosing Calc and Alk for over a year with no problems. I just added the third for dosing H202. It's the most economical way to automate dosing your tank. I wish BRS would find/carry a product that would allow me to put this on my Apex Energy Bars solid state outlets.

Bought two dosers rated at 1.1ml/min. Both were calibrated at 2.00ml/min.. No problem though as I expected some variance from specs and reviews shown in site descriptions. Units seemed well constructed and easy to use. Installed using mount brackets included and hooked up to a two outlet timer, set for 3-5 min runs during the night (2 part ) and have checked for accuracy several times since. Right on the money at 30 ml each for the 15 min total run times. Noisy? Maybe a tiny bit but certainly not a deal breaker unless you're running in your bedroom at night! All in all a great purchase for me!
Way off stated value, and very loud By Barnaby on 6/12/2017
Barnaby wouldn't recommend this product to a friend
I bought three (3) 1.1 ml dosing pumps plus other miscellaneous items, received them promptly from BRS in good order, they were well packed. I calibrated them according to the instruction and their rates are 1.88, 1,85, and 1.79 (ml/min). So they are way off the stated nominal value of 1.1, I know I'm not buying/paying for a scientific instrument but that give me doubt on the manufacturer's QC, if they have one.
The other issue is they are all very loud! They started quite in the first minute or two, but ramp up to loud clicking sound, sign of very bad design and/or construction of the motor and gears.
I'm from Canada so it will be hassle to return them, for now I mount them outside of the cabinet on a timer and that helps to reduce the noise. Only time will tell if they are durable and can keep a consistent flow rate in the long term, but don't be fooled by the overall 5 star rating, they are nowhere near a well engineered product.
