Apple's new MacBook Pro laptop has been greeted very warmly by experts and reviewers, being praised for its Retina Display and powerful innards.
However, DIY website iFixit has called the new computer "the least repairable laptop we've taken apart".
A special screwdriver is needed to pop off the bottom cover, much like the iPhone 4 and 4S, the website said.
"The lithium-polymer battery is glued rather than screwed into the case, which increases the chances that it’ll break during disassembly."
The RAM also received plenty of criticism, being soldered to the motherboard and thus leaving users unable to upgrade.
iFixit gave the laptop a repair score of 1 out of 10, saying: "On top of being glued together, the new MacBook Pro is virtually non-upgradeable - making it the first MacBook Pro that will be unable to adapt to future advances in memory and storage technology."
