It's a decision for you to make.
Personally I'd use Samsung.
Someone trying this could use a non authentic battery and also cause issues in the phone through the procedure and introduce dust etc into the phone.
Once the seals have been broken by a non authorised Samsung Engineer then Samsung may also decline any further support @thedarksideofHassan
