This is the most compact unit on the market which is it's unique selling point. The SD815iS has reasonable range with all the radar bands needed for general UK driving and it is what we would consider as an entry level unit.
WHAT WE LIKE
- Has been a perennial favourite for years
- The smallest unit on the market
WHAT WE DON'T LIKE
- More false alerts than we would like (though less than the cheaper models)
