A very large number of benefits, yet some small inconveniences.

Good value for money. Requires the contribution of rechargeable batteries because friction is significant because of the large number of gears, so the engine struggling and batteries run out quickly. The backhoe works perfectly fine except for changing the various functions because there is a defect in the construction manual, but this is easily arrangeable. I recommend this backhoe lego technic for any age: you have 10 or 60 years.
In addition, if you are creative there are many opportunities for fun constructions.
