Cons

•Bluetooth functionality is not very useriendly and relies on costly, subscription-based app software, which is not clearly disclosed upfront, reducing trust.
•The included lithiuon battery has reliability issues, including charging difficulties due to the need for a specific 5V 1A charger, which is uncommon and may not charge properly.
•True poino-point distance measurement is unavailable because the device lacks horizontal angle sensing.
•Accuracy beyond about 60 feet may decrease, so more critical measurements might require confirmation with a tape measure.
•Considered slightly overpriced given the feature set and software limitations.
•The free companion app is limited and requires a $14.99 monthly subscription for full functionality, which some users find misleading.
•Lack of modern charging convenience like US is a missed opportunity for improvement.

Bottom Line

The Bosch GLM165-27CGL is a solid, reliable laser distance measure with impressive green laser visibility and professional-grade build quality that excels at straightforward, accurate long-distance and indirect measurements. However, its software and battery charging options leave room for frustration, especially if you need seamless Bluetooth data transfer without extra subscription costs or you rely heavily on battery convenience. If software cost and battery quirks are dealbreakers, looking at competitors with better app integration and USB-C charging might be wise. Otherwise, this tool shines for pros needing a dependable laser measure that speeds up onsite workflows.
