## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Excellent customer service
  

*by M***S on Reviewed in the United Kingdom on 8 September 2016*

Excellent customer service. Having received an empty package from Amazon (the weight had clearly fallen out of the cardboard envelope) I was sent another free of charge by Five Star after already obtaining a refund on the empty package. The weight I received is very good quality finished in chrome and packaged in a handy container to keep the calibration weight clean and free from scratches etc. Would highly recommend both the weight and especially Five Star for the level of customer satisfaction.

    5 star product
  

*by J***D on Reviewed in the United Kingdom on 24 June 2018*

This calibration weight is excellent. It is acurate within a tolorance of 0.001 and works excellenty with my scales. I would buy this again, but I don't think I will need to as this product is so strong it is likely to last the rest of my life. And then some.Purcahse this for Smart Weigh scales.

### ⭐⭐⭐⭐⭐ 







  
  
    not what I needed in the end but still a good buy
  

*by R***N on Reviewed in the United Kingdom on 17 May 2016*

I ordered this to calibrate my digital scales, not knowing which weight was required for that model I followed Amazon's recommendation (customers who bought this also bought x). Unfortunately not the best recommendation as when the scales arrived, a 500g weight was required. I had to get another calibration weight (obviously) but am keeping this as it will come in useful for checking the scales' accuracy.
