Everybody has different feature preferences for UPS models.
Like most models these days, that particular one says “six outlets” but two of those are surge protection only, not on battery back up. In addition, that particular model does not have a USB charging slot, which is a feature I like.
Also, be aware that while the older version of that model did have a replaceable battery, the current version does not. Replacement batteries typically run around $35 for most UPS of a similar design, so it may not be worth it to you, but again speaking just for myself, I prefer a model with a replaceable battery.
My current favorite is the BE600M1. For about $10 more than the regular price of the 450 you get five battery protected outlets instead of four, still get two surge only, plus one USB charging port, and it has a replaceable battery.

But of course it’s $20 more than the sale price, So the budget price may make the 450 worth it to you – – it’s certainly a good deal.
And I have friends who won’t buy anything rated less than 850VA, so again, different things work for different people.
