Is My Ads Budget Too Low?

I hired a team to manage my PPC ads and they are performing horribly. We have several different ads running but for some reason, they’re keeping the daily budget pretty low: between $5 and $10/day.

The ads are barely spending. Most days they spend about $1 if not less than that. I’ve asked the team to focus on one SKU and combine the budget that is currently spread across 7 different campaigns but they are insistent that we keep the budget low.

Is the budget too low for the ads to perform meaningfully? I’ve read elsewhere that <$10 isn’t going to go anywhere.
