Many stimulation levels, vibration, tone and light in a remote collar made for one dog. The listing gives no neck size range, so fit is worth confirming.

Overview
An owner training one small or medium dog gets a remote-controlled collar with a biothane strap and a receiver. The remote has a finger clicker, and the charger, contact points and lanyard are in the kit.
The reason to look at it is the range of levels with vibration, tone and a light, which gives a trainer several cues to work with. The limitation is the single-dog setup and the missing neck size information.
Who it's for
People training one smaller dog who want waterproof, rechargeable hardware will find the level range useful. Owners of large breeds, or anyone who dislikes stimulation collars of any kind, should look at other training tools.
Pros and cons
- Many stimulation levels
- Vibration, tone and light
- Waterproof and rechargeable
- Finger clicker on remote
- Single dog setup
- Neck size range not listed
- Accessories carry a shorter warranty
Performance notes
The remote sends the chosen level to the receiver on the strap, and contact points carry the stimulation to the dog. Range depends on terrain and obstacles, so the stated figure is a best-case open-air number. Rechargeable cells need charging between sessions.
