## Product's reviews:
- Grove gear - ordered it got a week early was exact to the specs performed flawlessly
- 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.
- Right on - Took a bit to ship but after it shipped I got it fast. Right product.
- Gearbox gold - Great Gearbox, great price, free shipping!
