    Works fine

    Review by on Mar 6, 2014

    We have only been using it for a few days, but it works well, and should not rust out like the last type we had.

    Easy to set up and use. I have 3500 baby blue Eucaliptus plants so it gets a good work out. So far so good.

    Couple of hiccups - otherwise fine

    Review by on May 1, 2013

    Very similar story to previous reviewer. I just bought two of these to replace old A30s that had been running in my greenhouses for many years but had become less reliable at lower volumes. The SuperDos 20 with the fixed lower end seems to be the least expensive option and easily handles the volume of water I need to put through it. I had two small problems with the one of the new ones: 1. It arrived with the input hose adapter broken off (I think this is a packaging issue - there isn't enough protection at the end of the box - QC was very prompt about replacing it); 2. After a couple of weeks use it started making a screeching sound. I unscrewed the lower end and a wing had broken off the gray clip that holds the dosage rings in place. I replaced it with the spare that's included in the box and flushed the unit through and it appears to be working fine again. Otherwise good performance with minimal setup.

    Does the job

    Review by on May 24, 2012

    This is my second Dosmatic (previous one wore out after 15+years of use in a greenhouse). This was easy to set up and use in my watering situation (have approximately 500 orchids which are watered several times a week in the summer and less frequently during the winter.
