With SUS, you have some room to play around with the words without effecting the results too much.
For example, you could change it to:
I think that I would like to use this service frequently.
I think that I would like to use this product frequently.
Whatever works in your context.
This is backed up by this article.
Small changes are less likely to have a big impact. For example when using the SUS, it’s been shown that changing the word “system” to the name of the product (e.g. QuickBooks) or the type of system (e.g. website) adds clarity for respondents without sacrificing its psychometric properties.
