Battery Rivet Gun for standard rivets up to 6.4 mm (1/4)

I am retired yet still make various projects in my (almost) fully equipped home workshop. My hands suffer from arthritis and lack a lot of strength. After making a project recently that used 4.8mm steel rivets and now looking at a couple more projects, I thought it would be time to get a cordless electric riviter. I have many Metabo cordless tools and so my first thought was to look at what Metabo have as a riveter. Wow, over $1,000! That's too much to justify. I looked further on the internet and a lot of other brands were the same or even north of $1,500. I would also have to buy a battery and charger to suit. Then I come across Huckbolt. They had expensive (for me) options as well, but then I saw this one. No name, but the figures (15kn force) of what size rivets it could manage and the plain review and assessment by Huckbolt was very reassuring. The best part was the price, a bit over $600 including freight. With charger and two batteries! It arrived in about 2 days, very quick to country NSW. I have used it on a project now, using 4.8mm steel rivets. Wow, this thing just is amazing for me. No struggle, the rivet is held straight on the job while squeezing the trigger. A clean snap, and the rivet is so perfect.
I may not do 1,000 in a year, so it will last me for good.
The finnish of the tool is a bit on the rugged side and not as refined looking as the Metabo. But the quality is there, the strength of the tool is 15kn as against Metabos 10kn. It is half the price, if you factor in a battery and charger for the Metabo.
I am very happy with this tool, its quality and strength. I am quite sure this tool would go well in a commercial workshop, so long as with any brand, you keep it oiled and maintained.
