Got my gripper in on Friday night, and got batteries for it from my local vape shop on Saturday. Everybody that worked in the shop had to try it before I even got a chance to. None of them had seen it. Once I got to try it though, I will say that it works great! I'm very happy with it. Using my 6.5 ml DCT with a smoktech carto, haven't had any issues. For the price, it'll be hard to beat.

Equipment:
All measurements were taken at approximately 5 seconds on time after the voltage had steadied. Error tolerance approximately +/- .05V due to voltage oscillation.
Full Charge Battery Input Voltage:
Half Charge Battery Input Voltage:
Full Charge Voltage Graph:
Full Charge Amps:
Full Charge Watts:
Full Charge vs Half Charge with 1.5ohm Dual Coil Carto
Full Charge vs Half Charge with 2.2ohm Single Coil Carto
Full Charge vs Half Charge with 2.8ohm Single Coil Carto
Summary:
The VV Gripper is well regulated and capable of consistently delivering between 4 and 10 watts throughout the tested battery drain cycle. This will more than satisfy the vast majority of vapers. It does not hold up to its advertised 4 amp limit in any condition that I could test, and the max amps vary depending on the resistance. At the higher voltages where the "limit" starts to level off the voltage, the "limit" does not seem to follow any set values within the scope of this test. The closest thing that I could call a loosely defined limit is approximately 12.5 watts with variance depending on resistance.

Alright, just watched PB's review and now that I know it is a raw square wave PWM I can adjust the watts chart to account for RMS voltage. This will reflect the "hits harder at lower voltage" phenomenon that these PWM devices have.
Edit: Done. That's quite a bit difference. Hats off to Rocketman for pointing out the RMS factor.

This works for me.
I only vape around 7-8 watts and I'm so over the tube mods, especially since I already have 3.
Rader, thanks for the charts/graphs, I like numbers

Funny you should ask, I dropped mine at work today. 3 of 4 corners popped open, the 4th is being stubborn. I want to open it the rest of the way to see if I can identify the regulator chip. I'll take pics when I get it open.
Just got new gripper this morning, would have to say, best bang for the buck yet. Got a phoenix on top, loving the ohm's indicator. Size is beautiful. Have to say I am impressed.
The battery indicator has been pretty awesome too. My 1800 mah protected batts have been lasting me 2 days before needing charged. Loving it
And this is one of the reasons why I hesitate to get into any kind of variable voltage or device with separate batteries. I'll screw up and blow my hand off. This is all so arcane to me.
Spare Batteries anyone? Type search imr 18650 on ebay, there is a lot of five imr 18650 for $10.99. I purchased these, received 4 1600 Mah reds and an AW 18650 2000Mah. Charged them, and seem to be just fine, all worked and are at 4.2v after charge.
I would be hesitant to call those genuine AW, or even IMR. Hard to tell from the pic, but it looks like at least a few of them have a large button where a genuine AW has a small button.
Genuine AW on the right in this pic from SuperT:
If there is any reason to doubt, I would not use them. You could possibly be playing with unprotected ICR batteries.

Anything could be a fake, but they appear to be IMR's, and The one that is tagged AW appears to be one. Just thought I would pass along, to those of us who do not want to spend much on batteries if we don't have to.
Hey I wouldn't worry about them at that price and they work. I bought six panny batteries in a co-op and they were customized so ended up a fraction longer than regular Panasonic's and they don't fit in the Gripper properly. They fit but the door doesn't close good so I'm afraid to use them much because if the batt door breaks the Gripper would be useless. I would have been better off with your deal.
For 10.99$ it could go in the trash, but was worth a shot. Seems to be good at this point, so thought I would share, lord knows this stuff nickel and dimes us to death.
4 out of 5 of those are fake, the 1 on the left looks genuine (AW dont make flattop batteries)
I am no battery expert, but I have noticed many vendors are selling these with the option to purchase ICR batteries and charger as a kit.
If the device has built in protection then why would ICR's be so bad.
Sure double protection would be better, but I aint wearing 2 condoms either....lol

The amperage at the battery is going to stress an ICR much more than a high drain battery. ICRs will work but it takes a toll on the batteries. Depending on the efficiency of the regulator, amp drain at the battery could be over 5 amps for the high watts crowd. If they are using a 2400mAh battery then they would be over the usual recommended 2C discharge rate for ICRs.
Also, due to length restrictions, if an ICR can fit in the VV Gripper chances are it is and unprotected battery.
