## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    I would buy more if I only could.
  

*by S***I on Reviewed in the United Kingdom on 16 April 2020*

Sound is crisp. It needs very little tension on the recorder too. My old Teac X-10 needs some help with motivation on its pinch rollers. This is the only tape which still plays good.

### ⭐⭐ 2.0 out of 5 stars







  
  
    Tape stretches
  

*by K***8 on Reviewed in the United Kingdom on 25 May 2023*

Bought this brand as have used them in the past. This tape is so thin that it has stretched so much after only 3 run throughs that the audio now suffers from wow and flutter. The recording isn’t worth listening too. It is a shame that this brand has gone downhill so much. My 50 year old tapes still play nicely.

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    HAD TO ADJUST THE INFRA RED SENSOR IN MY MACHINE, AS THE TAPE WAS LETTING THE LIGHT THROUGH!
  

*by T***  on Reviewed in the United Kingdom on 23 November 2022*

Very thin translucent tape! When I fitted this tape onto my Revox, the machine would not run.Put old tapes on and noticed immediately, the machine would run ok.Found out that the infra red sensor light was SHINING right through the tape stopping the machine running.Removed the  back of the machine, located the SENSOR POT on the circuit board then adjusted it, the machine would then run!Ok now, but was a bind sorting out the problem.'E'
