ATS backrivet sets

Anyone here tried all three 12” offset back rivet sets available on the market today?

I’m currently bucking RV10 top wing skins(AN3 rivets).

I’m well versed in the methods required when using the various offset rivet sets. My cheap self bought the ATS 2470-12D at $32. The tool seems to be made of garbage Chinese toffee metal and really struggles to get the energy down to where it counts.

I see ATS also has the 4653 12” double offset back rivet set at $55. Hopefully made of higher quality tool steel?

Lastly, Cleaveland tool sells one for around $70. It’s made by Avery and hopefully of higher quality tool steel.

Thanks for any input you fine folks might have.

I found any longer, or offset, tool requires higher pressure to set rivets.

I tried the long, double offset technique. I gave it up when I realized a mushroom set and a small tungsten bucking bar was better.

YMMV
