Love mine !!
I have a Olympic giant, and a Hosui in my yard that are on their 4th leaf. They fruited on their second leaf (picked them off @ dime sized). This year, I let the Olympic giant keep 15 fruit and picked off 30 this spring. The Hosui is much bigger in height and diameter. I kept 45 fruit this year and the kids and I picked off 205 dime sized fruit this spring. These were grafted trees on OHF x 97 for the OG, and 87 for the Hosui. The 97 is 1/6th of the size right now for whatever reason....
We really like the taste of them. They store bought ones don't really compare in flavor. I have never been impressed with the store bought ones, but the ones from the yard trees are up their on my list of all fruits
I have never sprayed, and haven't noticed any bugs on them, or any imperfections on the leaves of any sorts. The peach trees that are 20 yards away were beaten up by Japanese beetles this year.
