    All in all it’s fine. If you are familiar with RODI systems
    I used this as a replacement and upgrade to my 50 god system. Upon arrival which was lightning fast I noticed just the filter inside the box. This filter as shipped is not ready to go and does not include the components Or any form of instructions needed to get it working optimally. The flow restrictor valve was not present and the 6th stage filter was not attached or installed. Although after reviewing the purchase on ebay i noticed that the seller would include that if asked. It’s small print and easy to miss as I in fact, did. If you do not know what you are doing I would not advise this filter. I had the required parts needed and was able to get it running normally. If you are familiar with RODI units and running tubing and connecting the filters in correct operating order you will have zero issues. Some things to point out. The seller includes a ball valve that in a pinch you could use to restrict flow. This should not be run at full bore as it will not pressurize the RO membrane. Get a flow restrictor valve instead. Attaching the 6th Filter or stage is easy. Just remember that there is an in and out to these filters. The fitting on the top screw off portion of the filter is the inlet and the bottom is the output. Same thing for the rest of the stages. this unit does not include any sort of check valve. Plan accordingly. Although available elsewhere it does not include auto shut off valves DI resin depletes far too fast and does not seem to actually be installed correctly. After one hour all color was gone indicating time to change. There were also huge gaps with no resin present. I dumped it, replaced it and packed it extremely tight as it should be and all is fine. Not for the novice and as is needs work and parts for the reef tank deployment or drinking water systems.

    Difficult at best and does not deliver all promised in this ad.
    Shipping, Shipping was fast and ahead of schedule. Packing was top notch. Product I opened the box excited to build this project. After a very confusing assembly process I began to realize that the instructions are for a different board and none of the connections it tells you to make caue the printer to work. For your conveinvece you should be looking for drivers and schematics for the GT2560 - Geeetech. This will allow you to get close. to final. if your board works. As Advertised materials. Toolset -I am dissapointed at best with what is said to be included and what is included. It is advertised here that you will receive a toolset. and a decent looking toolset at that. In reality what you get is 4 allen wrenches and a cheap flat head screwdriver. Filament. As advertised it says you get 250g of a random color free. In reality you dont get anything. of the sort. SD Card- This is false and apparently where the software is for the product. However you will not receive this so dont get your hopes up. Power Cord. Included as promised. Software. As advertised it says that this unit will print .gcode and .stl files. The SD Card reader reads only .gcode files. No other file type works. .GCODE ONLY Folks. Not to mention I received no software so I can only print from an SD Card and this is perhaps the only reason I do not file claim with Paypal for a chargeback! Overall I am not in anyway happy with this product. It is not advertised correctly or assembled correctly when you use the directions. (I only assume because after 3 days trying to guess and research this I am still not printing) Be warned You WILL see your printer fail on every level.
