What to know before buying

Listing details to confirm

The listing is inconsistent about identity: the title and manufacturer part number say TP350, while the model field says TP357. It also labels the colour as “Bluetooth”, which does not identify a colour. Confirm the exact selected model and finish before purchase. The stated dimensions appear under different dimensions fields, and range, accuracy and battery-life figures are manufacturer claims rather than independently verified measurements.

Aggregate ratings are mostly five-star, but a notable minority are one-star, so overall sentiment is favourable without being uniform. Ratings alone do not explain what buyers liked or disliked, and they do not establish the accuracy, Bluetooth range or app performance of this model.
