The Taylor K-2005 is a wonderful kit in every way except one. It doesn't have the FAS-DPD chlorine test, instead it has the regular DPD chlorine test. The DPD test will only test chlorine up to 5, while the FAS-DPD test works up to 50. If you are shocking the pool you need to be able to test well above 5, up to 15 or 20, so it is much better to have the full FAS-DPD chlorine test.
If the price is good enough you could add a separate FAS-DPD test kit, TF Test Kits has the FAS-DPD test available separately for $23. But it will probably be a better deal to get the full TF Test Kit, see the link in my signature, which not only includes the FAS-DPD chlorine test but also has larger quantities of all the reagents.
