1st Razer blade stealth 512 4k: broken mouse tracker, 5 days worth of emails and reinstalling razer synapse. 1 month later after shipping and emails 2nd Razer blade stealth 128 qhd: broken fan that is choking from its innards. 1 month later 3rd Razer blade stealth 128 qhd: left fan seems caught in something, scratches on charger and side of usb c port. Wont charge. (felt cheated after spending good money to get a used broken system) Awaiting for another replacement (wanted refund with free shipping). They will not back up their product. Conclusion: i will keep doing RMA till they send me a decent product, then debate if i want to refund it after i can play with the RBS for more than 4 hours without something going wrong. Tell me guys, how much tries till you got a decent RBS?
