Anybody knows the diameter of the sd43 case back. I want to buy a toolset on ebay to open the back but the set i saw has maximum of 29.5mm.
Set includes the following sizes:

NO.0--18.5mm
NO.1--20.2mm
NO.2--22.5mm
NO.3--26.5mm
NO.4--28.3mm
NO.5--29.5mm

Anyone knows if this is good quality or not worth buying

I bought one of these case opening sets from AliExpress, and the quality was just terrible. The 29.5mm case opener would not even fit my Noob v7 Sub.
I did try to use it, and it put some 'nice" scratches on the back of my case.

Kept me wondering.....was the case opening set off, or was the case back of the Noob v7 off?

I suspect the first.

I ended up throwing away the whole case opener set.

Would like to hear the experiences from others on this.

I bought it too. I don't think it's good - but it's probably just about good enough. The fit doesn't seem to be as precise as it should be and the size is a tiny bit too small. Consequently I find I have to really push down hard on the tool to ensure it grips the caseback properly without slipping and scratching. I've used it on the same watch as you OP so it does work, just.

They're way too tight. Mine was at least. I couldn't budge it with my sticky ball, hence having to buy the tool OP is looking at. Even with that, it was quite tough.

I used a super ball. Thos $5 balls to remove case backs. Took the sd43 back off easily.

and looking at this vid , it does appear to be the same size as the sub (29.5) , its no where near the size of the DSSD caseback (36.5) look at 3:06 to 3:15 in the vid
