These swabs would be excellent for general laboratory and classroom use and for routine forensic work. The packaging is a bit dated (i.e., 1000, 2-swab packs in sterile paper wrappers shipped in a lightweight carboard box). Upgraded packaging might be an improvement (ex., both the box and the swab packs should be re-sealable and waterproof, swab heads could be pre-scored for easy breakoff, etc.), but this might increase the selling price of the product which is currently its most attractive feature. All-in-all, this product offers excellent value for money.
I had a battery powered nebulizer that worked well until it failed. I bought this to replace it. I don't believe it will ever fail, but it doesn't suspend the liquid as well as the battery powered one.
