Disappointed with Basilisk X Hyperspeed

I use the mouse in 2.4GHz mode (not BT) and experience random "death" of the mouse that only removing and re-inserting the battery fixes. This can happen intermittently WHENEVER. Even in the middle of a battle. Then it doesn't happen for a day, or for a few days, and some other day it can happen twice. With this kind of behavior, I cannot even return it to the shop and claim a warranty issue, as I cannot be sure they can actually verify the issue (it can take days to happen and no lab will spend days using my mouse to figure this out). I am "trapped" with a bad product. - Mouse it about 8 months old but started doing it even from the early days. But since it was very intermittent (sometime even not doing it for a week), I just gave it time. Bad decision. - Mouse in a perfect condition, no drops or misuse. - Changed battery many times already. - USB port I use for it is 2.0. - It is already on latest firmware. - Win 10 x64, with every update and latest mobo firmware (Gigabyte X570 UD). Help? Well, as I read on the Net, the issue (with slight variations) is not uncommon, yet Razer didn't seem to react. My son insisted on Razer so I gave the brand a try. Probably last Razer I buy. Except if I witness some extraordinary company support (for which I don't hold my breath).
