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

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.
Excellent piece of equipment. By Donnie on 6/12/2017

Easy to use good quality. Bought 2 doser's and when calibrating found that both mine dose at 1.5 ml per minute. No big deal both are accurate and the same.
Constructed well By EAN on 3/15/2017

First, I must say that I love BRS customer service and their focus on customer satisfaction. The BRS doser is well made as far as construction and the pumping is on target at 1.8 ml. The problem I experienced was a knocking noise from inside of the pump. Customer service immediately sent another pump overnight. I give customer-service five stars, but only two for the the BRS doser. I worked for years in manufacturing and things will occur, despite using good QA measures, and the difference is in brand name and customer service.
Loved the idea By Ernest on 3/14/2017

I love the BRS company and they stand behind their products much more than others in this game. Unfortunately, I have had some bad luck with this dosing pump. The first purchase had something rattling around inside and BRS offered an immediate replacement. The replacement made a loud knocking noise during the 10 minute run to determine my flow rate, which was 1.8.
I contacted BRS and was immediately sent another dosing pump. The replacement made the loud knocking noise immediately after setting up (flow rate was also 1.8). I plan to return the products and explore other dosing pumps BRS has available. I currently have a DOS, but needed an additional pump to daily.dose no pox. I currently manually dose mg, but plan to auto dose in the near future. The dosing demand for no pox and mg are low so another DOS is overkill cost-wise.
Again, I will mention that this issue is not reflective of other products I have purchased from BRS! However, please note the great customer-service I received that is bar-none to others in this hobby
