## Product: Bosch GLM165-27CGL Laser Measure
**Brand:** BOSCH

## Pros
- Ideal for measuring large areas and long distances up to 165 feet with excellent visibility thanks to the bright green laser, even in daylight or crawlspaces.
- Highly accurate and consistent measurements, making it suitable for professional onsite use and saving considerable time during takeoffs.
- Simple setup with a clear, easy-to-read screen and intuitive rubber buttons providing satisfying tactile feedback.
- Rechargeable 3.7V lithium-ion battery included, with the versatile option to switch to AA batteries as a reliable backup.
- Features a tripod mount and built-in inclinometer that allows indirect height and horizontal distance measurements using Pythagorean calculations.
- Bluetooth connectivity allows transferring measurements to a computer for creating 3D shapes; works well with third-party apps like Measure Square.
- Durable, professional-grade build with a lightweight and solid design reminiscent of quality Bosch power tools.
- Quick unit conversions and a confirmation buzz add convenience during use.
- The simple and efficient user interface requires little to no instruction, focusing on practical field use without overwhelming software complexity.
- The integrated level is helpful for measuring sloped surfaces accurately.

## Cons
- Bluetooth functionality is not very user-friendly and relies on costly, subscription-based app software, which is not clearly disclosed upfront, reducing trust.
- The included lithium-ion 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 point-to-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 USB-C 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.
