## Product's reviews:
- Enginiering - got what I need it the first time. no hassle, friendly customer service, communication is excellent, I am happy with the delivery time.
- Gear box - excellent service, fast, easy, and customer service outstanding,
if any changes they call and let you know,
- Replacement for an obsolete gearbox - We needed this gearbox as a replacement for an obsolete model made by Grove Gear back in the 90&#39;s. Needed to call the company to find out the equivalent and they directed me towards MRO. If this one will last as long as its predecessor I&#39;ll be retired by the time it will need to be replaced again.
