Hello HKJ,
I hope, you are still willing to review NiMH batteries, because I found an interesting new manufacturer

For this price, I would call them neither cheap, nor expensive.
I ordered one 8pcs set of these batteries, and I did a CDC test for capacity and IR with my Miboxer C2-4000 charger, which resulted the following: 1. 984mAh, 59mOhm; 2. 981mAh, 68mOhm; 3. 1004mAh, 56mOhm; 4. 963mAh, 66mOhm; 5. 973mAh, 73mOhm; 6. 970mAh, 55mOhm; 7. 982mAh, 57mOhm; 8. 960mAh, 57mOhm.
I think, these values are pretty good, when considering, the test was made just after opening the package, and found them at around 1.24V (I did no charge/discharge cycles prior to this test), AND, the discharge measurement was not on a minimal current, but the current the Miboxer C2-4000 offered for the test.
Also, I had a similar test run on these batteries:

While my test results were somewhat short of the declared capacity, I think, they are also not bad: 1. 2318mAh, 47mOhm; 2. 2358mAh, 48mOhm; 3. 2357mAh, 47mOhm; 4. 2346mAh, 48mOhm; 5. 2348mAh, 48mOhm; 6. 2334mAh, 48mOhm; 7. 2355mAh, 46mOhm; 8. 2354mAh, 49mOhm.
After seeing these results, I ordered a small pile of these batteries, too (just a few days ago):
