Actually the 2.5W is probably the part of that which would worry me least! As others have said VHF range is determined by many factors, or which the transmit power is quite low down the list (all other factors being equal a 2.5W transmission will be received with 1/2 the strength of a 5W transmission so only in the most borderline cases will that make the difference between a message being received/understood and not. The reality is you probably have no other factors in your favour though (height, distance to receiving station, aerial gain etc.)!
Uniden are not a prevalent brand on here for VHFs. I don't believe there is anything fundamentally wrong with them, but like midland, cobra, etc they are marketed at a price point. For many users the functionality will be fine, e.g. a yacht tender talking to it's mothership, a group of kayaks talking amongst themselves, or for people calling a marina or bridge at close range and even for use in busy areas with lots of yachties (tall masts = good range!) such as the Solent in summer!
If its only 2.5W on a feature easy to market like "power" you can assume they've cut the spec on all the other components that are more subjective like antennae design etc. My experience with low cost handhelds (which seem to be repeated by others here) is that when you get really cheap the water proofing is a feature that is compromised. Even if it has a good warranty that will be of little use to your inheritants!
