I bet if they had used a Mitsuboshi timing belt in the first place it would have lasted much longer.
Pros: would have lasted longer
The only thing I concerned was the timing belt itself. It was a US made MITSOBOSHI instead of Japan made one. But it was perfect fit, didn’t miss timing even by 1 teeth.
Pros: perfect fit, accurate timing
Cons: US made (initial concern)

Had the timing belt replaced last year - didn't find a single crack on the old one despite it being 20 years old. Ditto for the serpentine belt. The dealer's head technician had told me that Mitsu's rubber quality is top notch - on par with Toyota, way better than Nissan's (his words). I didn't believe him until I saw the belts with my own eyes.
Pros: no cracks after 20 years, top notch quality

It was a 10 piece kit and ended up being about $195 after tax and took about 3-4 days for shipping from Japan. It was one the most common kits you see with the Mitsuboshi timing belt. No complaints, worked out great, good price for the amount of parts it contains, and everything seems to be quality Japanese aftermarket parts.
Pros: good price, quality parts

I used to always go with OEM Honda parts for timing belt and water pump jobs. But the price of the OEM parts have gotten so high that I went with [this kit] on Amazon for my last TB job on my GSR, in late 2018. Mistuboshi timing belt, NPW water pump, GMB tensioner pulley. Those are all Japanese OEM parts suppliers, so I was comfortable using them. Almost 20k miles on thost parts now and everything is working great.
Pros: working great

He had installed an OEM manufacturer Mitsuboshi timing belt, and it snapped. Apparently it was a knock off. He reinstalled the old belt. I disconnected the injector to the cylinder with a bent valve, and drove it 200 miles home, on 5 cylinders. It actually ran better when I plugged the injector back in, When I got home.
Cons: belt snapped, knock off
Vehicle:
Honda
The cheapest I found to replace the timing belt back then was nearly $1000, and it was due at 60k miles, not 100k like other brands.
Cons: expensive replacement, short service interval
Vehicle:
Mitsubishi Galant
Mileage: 96560 km
