For a month I tried 3 riveters at a price of up to 1000. The first one broke after 3 rivets. The second "Matrix" broke after 2 rivets. Replaced with a similar one and broke after 15 rivets. I didn’t remember the third company, I turned it in my hands, I tried to rivet it, I didn’t like it, the mechanism stuck, the handles were crooked. I handed it back to the store. I found this one on the Internet based on reviews (not on the market). And lo and behold, the case, the rivets are included, the quality is immediately visible. The mechanism works without sticking, the paint does not peel off, the 4.8 mm trial rivets were installed with little effort compared to previous riveters. I recommend to buy. I took for 1450. with delivery to the point of issue.
