Dont know about researchkits.com bro. I have had nothing but bad experiences with them. This is just my opinion though. I will never order from them again. 5 orders they sent me the wrong filter ,that was worthless. I wrote them and they did nothing to correct any of the orders. They never even responded to the e-mail. I have had several bros with the same complaints. I had to pay for the correct filter. They didnt have a problem sending the right one after I wasted money on the kit and had to pay for a single filter. They suck in my opinion. I would stay away from them.
