Took a dive recently and ordered a very cheaply priced gimbal head in the famous Chinese shopping website. Qing Zhuang Shi Dai (轻装时代）Q45 gimbal head was purchased and shipping took all of 2 days to arrive at the doorstep of my apartment in China. Not at too much liberty to say exactly how much the head costs, but I can say it is under 100 SGD. And yes, it comes with the quick release plate as seen in the picture below. Size of quick release plate is 76mm x 38mm.
The Q45 weighs 1.7kg and has a claimed weight load of 20KGs. It comes with a main knob at the top to control the tilting friction and angle. It also comes with a knob near the base to control the friction on the panning action. It also comes with an height adjustable arm, very interesting feature, especially at this price range. The quick release clamp is said to be acra-swiss compatible and it comes with a plate 76mm x 38mm. The plate is fitted with safety screws so it will not slide off the gimbal when not in full release mode.
The main arm is aluminum alloy spray coated with a rubbery material. I have to say the rubbery material feels a little cheap to the touch but it does feel solid and can protect against knocks and dings. Overall the constructions looks a little rough. You will see bumps and marks on random parts of the gimbal, but nothing that hinders the workings of the gimbal.
A quick look on the product card... lo and behold! Q45 is made by Beike. So this is probably a re-brand of the Beike BK-45.
