Customer Reviews
Great customer service
Rick was wonderful setting me up with parts for a project for a film studio. He was able to provide quick advice for a part that wasn’t functioning as expected and recommended a replacement part quickly. I’m happy they are carrying the REC BMS and have them in stock! It’s a very solid system that’s easy to interface with!

Easy to use website
Fair prices for what I needed and easy to make sure I got all the accessories I needed due to the format of the product page.

Great customer service!
OGSS was there to answer all of my pre-order questions and their communication response time is top notch. Great people to work with and I’ll be ordering from them again in the future.

Thanks Matt!
REC-Wifi unit inoperable
I purchased the rec-wifi on the advice of and the REC website. I could not log into the wifi unit referencing the product manual. I found many individuals were having the same problem through a web search. In the end, I purchased the pc software which allowed for me to change the parameters associated with my specific system. My understanding is that one cannot do what with the wifi system. The touch pad also just displays information, it does not allow one to alter the bms parameters.

Hi Tom, sorry you had issues with the WiFi module. Early versions did have some issues but not recently and your situation seemed unusual. Hopefully Tine at REC was able to get your WiFi working for you in the end. The WiFi module, when working, will actually provide all needed functionality but you are correct, the LCD screen is for viewing only.
Excellent Service and quick delivery!
Had to clarify a few things before we placed the order, Rick was very responsive and helpful. Will definitely buy again in the future.
