You need to just buy extra batteries (CR2032). They last around six months for me with light daily use. **Q: What is the beats per minute range? Does it go down to 30?** A: The BPM range goes from 30-250. Hope this helps! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works as Expected *by on Reviewed in the United States August 5, 2026* Works as expected. Perfect for Marching Band practice. ### ⭐⭐⭐⭐⭐ An awesome upgrade from the Boss DB-88! *by on Reviewed in the United States February 21, 2012* I have been using the Boss DB-88 metronome previously. I used that model since 1999 when I was in my high school drum line. It was a great metronome to use in a drum line as well as playing a drum set. I eventually bought my own in 2003. The DB-90 has been out for a while now - I remember wanting to get it as soon as it came out, but I figured I'd wait until my good old DB-88 stopped working.Unfortunately, that time as come (after using my own for nearly 9 years!!!)The DB-90 is packed with SO MANY more features compared to the DB-88. I won't get into them all here since you can find them in the production description. I'll just say that the biggest upgrade for me going from the DB-88 to the DB-90 is the amount of memory slots you get. I have been used to only having 8 slots for so long. I was always struggling to figure out which times to delete from the metronome when I needed more room. Luckily, the DB-90 comes with 50 memory slots! I no longer need to decide which times to get rid of, because I have WAY more than enough room to save all of the times that I need!All-in-all, this metronome is a great replacement for the DB-88. I am extremely satisfied. To anyone who is looking for a metronome that will help you grow your skills, this is definitely the one. It has a great range of features that can help basic to the even most advanced players progress with playing to a click. I don't think any other metronome is as good as this... Boss knows has to produce perhaps one of the (if not, best) metronomes in the industry. I have been playing drums for 19 years to date, and I cannot recommend any other metronome as much as this one.My vote: BUY IT - You will not be disappointed! ### ⭐⭐⭐⭐⭐ Doctor Beat by Boss results in the best rhythmic education you can have. *by on Reviewed in the United States November 20, 2025* The best metronome for developing a sense of pulse and also allowing you to decipher many rhythmic combinations; I recommend purchasing it along with the charger. ## Frequently Bought Together - Boss DB-90 Dr. Beat Metronome with Tap Tempo - MaxLLTo 6ft 9V AC DC Power Adaptor For Roland Boss DB-90 DB90 Metronome Dr Beat Wall Charger Supply Cord - SMALLRIG Super Camera Clamp Mount, Double Ball Head Magic Arm Adapter, Fence/Desk/Tripod Mount for Monitor/Light/Camera, for Insta360, for Gopro --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/3042577-boss-db-90-dr-beat-portable-metronome-db-90-black](https://www.desertcart.hk/products/3042577-boss-db-90-dr-beat-portable-metronome-db-90-black) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-10-25*
