Everything works great so far. Batteries hold a charge well and seem to last as long as other brands of LP-E6 batteries. Only time will tell how well they last charge cycle wise.
Love it but...
Bought SliderPLUS Pro, Jib-One, and HeadPLUS. Thrilled with what they do. Wish it simply came with plug-in power. Don't have any other equipment that requires unplugging battery to turn off... so I forget and then have to wait while charging batteries on the next shoot. $60 ($19 each) to power up some fairly spendy equipment (hmmm?). Never a good idea to link frustration with your product. Would be a SOLID 5-star if it came with plug-in power.
