Trend Airshield Pro Spare/Replacement Rechargeable Battery for 8 Hours of Operation, AIR/P/4

Working ok does the job intended for

A replacement battery so you don't need to stop working when the battery in your helmet is flat. It always happens when I am at the point where I don't want to stop, I want to finish the bit I am doing

Does what it says on the tin but is RIDICULOUSLY expensive for what is a rechargeable battery in a cheap plastic casing.

First class service, delivered in good time exactly as requested.

Thought my battery was at the end of its life. When stripped found that wire had burned out. So keeping replacing battery as a spare but very happy with battery and service provided thank you

Very expensive--- overpriced

Using the daily means that 2 batteries are needed. Charging time is quite long compared to most professional batteries. Last a good 8 hours.

These batteries are not 8 hours like the description says there are 6 hours as this is the second one sent out to me

Deve essere ottima MA la maschera non funziona. Vorrei contattare l’assistenza ma non so dove andare!!! È possibile avere da voi qualche indicazione?

It’s a add on to work with my sonal system

Works well

Works fine, but its life isn't a long time, especially for the cost.

I was about to toss my mask as it would not charge. I searched replacement parts and this came up in my search. It arrived the next day. It was easy to install and my mask once again works as expected. I’m glad there are appropriate replacement parts available
