Great hunting @kimsungmin. These are my personal opinions for this product. Thanks for sharing.
Pros:
Long duration battery.
Sensitive to movements.
Undetectable
Adaptable to any handlebar
You can track your bike anywhere in the United States and Europe
Cons:
Only available for shipments to the United States, the United States, the United States and Europe.
You only have Internet for two years for free, then you will be charged € 3 per month.
If the product is very popular, the thieves can meet him and locate the Sherlock.
You have to activate the Sherlock every time you park. It would be good if the GPS was always active, so if your bike is stolen you will know in real time where it is.
Thank you for your kind comments
