That's completely normal, I understand that. It makes sense to spread out your coins and store them in batches using different hardware wallet brands. Too bad that you didn't wait a few more days to purchase your Keystone. Black Friday is coming up. Keystone's website is already advertising Black Friday deals starting from tomorrow. You could have saved some money.
Now I have three hardware wallets, Trezor safe 3, Keystone 3 Pro, and Bitbox02. I use Trezor safe 3 and Keystone 3 Pro with the Metamask software to store altcoins, and use Trezor safe 3 and Bitbox02 with the Electrum software on a offline computer to operate BTC (this is already secure enough, so there's no need to use Electrum's multi-signature function).
