Powerball power gripper metal vs CoC (and HG)

Ordered the 200, 250 and 300lbs Powerball "Power Gripper Metal Series" grippers on Amazon and they arrived today.

I'm in the UK so can't get rgc measured so here are some rough measurements (in mm), where powerball gripper is PG and heavy grips are HG :

|Gripper|Spring diameter|Inside sweep width|Grip diameter|

|CoC #2|6.60|73|19.12|

|PG 200|6.49|68|18.24|

|PG 250|7.05|71|18.31|

|PG 300|7.56|69|18.32|

|HG 200|6.55|64|19.00|

|HG 250|7.07|64|18.95|

|HG 300|7.54|63|19.00|

The 250 is certainly harder than the CoC #2 with a thicker spring and similar sweep distance. Handle on CoC is slightly better but the PGs are surprisingly good quality, far better knurling than on HG. However HG 250 feels a slight bit heavier than the PG250, it's perhaps because the PG250 spring is set up a few mm higher (at ~3mm) from the handles than the rest of the grippers (all about the same: 1-2mm).

The PG300 feels much heavier than the 250 and similar or a bit heavier than my HG300, but I'd guess its average for this gripper. Will be interesting to compare against the CoC #2.5 that's on the way. 

My ranking in terms of difficulty (easiest first) would be:

1. PG200

2. HG200

3. CoC #2

4. PG250

5. HG250

6. HG300

7. PG300

Haven't worn them in so they may get weaker over time but they seem like great training tools - about half the price of CoC. I had heard these are essentially the same grippers as GripGenie so a PG250 would be a #4 for example. Has anyone confirmed this or checked the RGC? 

Here's a quick demo & narrow close of the 250/300: https://youtu.be/zTKf7IHDv6Y

I also have a very wide HG200 at 7.5cm inside sweep and my PG300 is 7.2cm wide and although I'm a few millimeters from closing most of my 300 grippers I find this PG very hard to close mostly due to its width. 

 

I remember last year trying to close the HG200 with a TNS and I got a cramp in my hand lol. Was much harder to close than the HG250 which had a narrower sweep at 6.5cm
