The Sealer Sales KF-400 HC Heat Impulse Sealer with Sliding Cutter is by far, the best item I have purchased to date from MyBinding.com. It is very well made with high quality materials and the fact that it works well, seals the deal for me (no pun intended). I like several things about the Sealer Sales KF-400HC Impulse Heat Sealer, including the fact that it is made by a manufacturer that offers several options to maximize the usefulness of this sealer. For example, when I did research to figure out which impulse heat sealer I should buy, I learned a very interesting tidbit of information. Small business production level impulse heat sealers that are best for sealing bags use a flat heating element and impulse heat sealers that are best for shrink wrapping use a round heating element. The standard heating element that comes with Sealer Sales KF-400HC Impulse Heat Sealer is flat and the spare one that is included with it is flat too. The good folks at MyBinding.com allow you to order this impulse heat sealer with the standard flat heating element OR with the round one. I chose to order this impulse heat sealer with the standard flat heating element BUT I also purchased a separate round heating element. So I now have the best of both worlds. Of course, this option is not available from all manufacturers and this is why I'm so glad that I purchased a Sealer Sales heat sealer because they give you several options. It is very easy to switch out the heating element depending on whether you want to seal a bag or do shrinking wrapping. Plus it comes with a really well designed sliding cutter too!!! I am very happy with the Sealer Sales KF-400HC impulse heat sealer.
