11.1 Watts, 2.8 Ounces, 410,000 RPM, Single Spray. Trend is one of the first W&H models to use the lighter weight materials accompanied by cellular optics. These can become blemished a bit cosmetically, which in no way effects the operation of the handpiece. These have a very similar turbine as W&H Synea and W&H Alegra. Available in standard 4-hole backend, as well as swivel type quick connect backend. Also, be sure to use a good clean water filter system with these handpieces.
