Dentists, are intraoral scanners worth the investment?

As a state of the art digital lab that completed the most model-free crowns in Europe within 12 months, we have seen first hand how IOS can have huge advantages over traditional impressions for a number of reasons.
Studies suggest that digital impressions reduce patient discomfort, are time-efficient and simplify clinical procedures for the dentist by eliminating plaster models and allowing for better communication with the dental technician and with patients. IOS can capture accurate impressions for fabricating a whole series of prosthetic restorations on both natural teeth and implants. IOS can be integrated in implant dentistry for guided surgery and in orthodontics for fabricating aligners and custom-made devices. Digital scanners never degrade, can be reused, are easily stored with your digital patient files and sometimes are accessible anywhere you have an internet connection, making the work of a dentist easier. ⠀⠀

However, as with everything, there are a few cons. With IOS, it can be difficult to detect deep margin lines in prepared teeth and/or in case of bleeding, but arguably the most off-putting thing for most dentists are the purchasing and managing costs of upgrading to IOS. Lots of dentists believe that if "it isn't broke, don't fix it", and are reluctant to change methods that have suited their style of practice for years. It can be daunting to change a way of working when thousands of pounds are involved. ⠀⠀
We are interested to hear what practising dentists think.
