Accidentally submitted same thread twice. Mods please delete this one.

Actually 4 times.

I was looking at this the other day as well. From what I could tell, the flow rate was the only difference.

The BRS is 1.1ml a minute and the drews is 1.5ml

I'm currently using one of each but I just recently got the brs. The drews has been working fine for about a year. No complaints with either.

IIRC from when I looked at them a couple months ago, the number of contact points on the internal tube is also different. BRS uses 2 rollers, drew uses, um... more.

There is a few other minor differences. The BRS doser has compression fittings to hold the hoses on, were the Drew's doser only has barb fittings. And the BRS doser has 2 rollers instead of 4 so theoretically you should get twice the life out of the santoprene tubing. But the Drew's has a really good reputation and track record. The BRS doser also gets good reviews. I have 2 of the BRS dosers and I like them a lot. I wanted the Drew's originally but they were always out of stock so I got the other ones.

Thanks.

Thanks for the advice. I will just get the ones that are a bit cheaper. I think they are running a special right now on one or the other.
