A bit of false advertising.... By Darrel on 4/24/13

Digital Aquatics says this unit has 4 controllable channels. What they don't tell you is that only 2 channels work when using "small pumps". When I had issues with the controller not turning off an air pump, this is what DA said:

"This is a common problem with small pumps. It is caused by a small amount of voltage being sent back through the pump when it is turned off. This causes the triac drivers used on CH 2 & 3 to click back on. This is not a defect in the PC4 and is caused by the device attached to the module. Channels 1 & 4 use relay's while 2 & 3 use triac drivers to control the channels, each type have positive and negatives which is why both are included in the PC4. The easiest way of solving this issue would be to move the device to CH1 or 4, if that is not an option a surge protector will also solve the issue. Some have also used 1' extension cables that have the lighted socket on the end as a solution."

This may not be a defect but it surely is a poor design.

Very good controller I am using it for my heaters only first the moment and temperature is rock solid .my only problems with this is not much info on programming and using the pc software. I wish there was more instructions on programming.

Disappointing and frustrating By Mike on 3/29/13

There are no instructions anywhere about programming using a PC. You can't program all your modules while you have your PC plugged in because the PC consumes one port and there are exactly ZERO extra ports. This means you always have to have a module or sensor unplugged in order to do any programming. Of course you cannot program any module or use any sensor that's not currently plugged in. This is a huge design flaw for me.

You also have to carry ALL your modules over to your PC to program them. I can't imagine why they don't allow you to take only your head unit to your desk for programming but instead make you disconnect and remove every single thing plugged into the head unit and move it all to your computer. If you have a laptop it's easier but still not easy as you have to fight with the lack of a PORT!

I can't mount everything in a safe location away from potential spalshes because the cords are so short.

In short I believe the end performance may be ok as long as I never have a splash that gets the items wet.

The terrible ergonomics of the unit including the interface, lack of documentation, lack of a programming port, and extremely short cords make this a DON'T BUY for me.

This is a great "toy". Obviously you can have a successful tank without this product but it sure does add to the fun and does simplify things such as emperor urges, lighting and such. I was going to buy a digital thermometer control and a wave maker which would have came to more than this product alone. I like hooking up my laptop and making changes/ alarms. If there is one negative is that it only has 4 outlet slots with the lite series but I guess that is why it is the "lite" after all leading to the only reason 4 of 5 stars. I cannot control all the things I want with only 4 slots so I am already going to be purchasing a 2nd strip which puts me near the 200 dollar mark. I love it though that's for sure.

Great Controller, Instructions lacking By mupchu on 3/23/13

Controller was easy enough to install and program once I jumped online to get all the documentation that was not in the box. Also wish the USB cord was longer. Overall very pleased with the purchase, but DA could have done a much better job. Box should include CD, and manuals (including the myreef2.0).

My primary reason for this purchase was to run items in my sump/refugium. I feel the instructions were poor, but a guide non-the-less. I figured out what I needed to on my own by just scrolling through a d checking all the settings out on my own. I now trust my system to maintain a stable temp and for my lights to come on in the sump at the right times at night. The piece of mind this provides, with the possibility of expansion in the future makes it well worth the money to me.

Great Controller! By Phil on 3/12/13

I love this controller! Easy to use and install! Only way I could be happier with this is if I would have bought the pH probe and NET module

Nice Product By JOSEPH on 2/6/13

Have only been using this for a couple months, and I am sure that I am not fully utilizing itss potential. Not as easy as I thought it would be to program, and the box was smashed up from BRS - but the contents were just fine - had me a little freaked out at first, but no complaints. As the system that this unit is attached to grows, I hope to expand the RKL to perform more task (not just lights and heaters as I have it now, but it does do this flawlessly).

Good unit mostly! By Joe on 1/4/13

Unit works well. I am glad I bought it. Although it could be better! All the electrical plugs should be able to handle whatever I need them to not just two of the four on each strip. Also the alarms are very poor. You cannot adjust the volume and they are barely audible!

Worth it and then some! By Tim on 12/20/12

I was skeptical about getting one of these. Didn't figure I needed it. I have to say, though, that it makes things much easier. I have a 58-gallon mixed reef and have the RKL Basic set up to control my temperature, lights, and fan. It was easy to program (though I wish they had software for a Mac) and I'm no digital genius. Instructions? Not the greatest, but the quick start guide is really all you need for the "basic." And if you get into trouble, you can email DA or BRS. For about 7 years, I ran a kind of bare bones tank with pretty good success, but this thing is a game-changer. Probably the neatest thing I've ever purchased for my system.

The Reefkeeper is easy to setup and does everything mentioned in the BRS videos. I highly recommend this product to anybody. Thanks BRS!!!
