The 2020/2022 Notes Indenture, the 2024 Notes Indenture and the 2025 Notes Indenture are collectively referred to herein as the “Indentures.”

In connection with the furnishing of this opinion, we have examined originals, or copies certified or otherwise identified to our satisfaction, of the following documents (collectively, the “Documents”):

1. the Registration Statement (including the preliminary prospectus included therein);

Spectrum Brands, Inc. 4

2. the 2020/2022 Notes Base Indenture (including as exhibits thereto the form of 2020 Note and the form of 2022 Note) and the 2022/2022 Notes Supplemental Indentures;

3. the 2020 Notes;

4. the 2022 Notes;

5. the 2024 Notes Base Indenture (including as an exhibit thereto the form of 2024 Note) and the 2024 Notes Supplemental Indentures;

7. the 2025 Notes Base Indenture (including as an exhibit thereto the form of 2025 Note) and the 2025 Notes Supplemental Indenture; and

8. the 2025 Notes.

In addition, we have examined: (i) such corporate records of the Company and each Delaware Corporate Guarantor that we have considered appropriate, including a copy of the certificate of incorporation, as amended, and by-laws, as amended, of the Company and each Delaware Corporate Guarantor, certified by the Company and each such Delaware Corporate Guarantor, respectively, as in effect on the date of this letter, and copies of resolutions of the board of directors of the Company and the Delaware Corporate Guarantors, relating to the issuance of the Notes and the Guarantees, respectively, certified by the Company and each such Delaware Corporate Guarantor, respectively, as in effect on the date of this letter; (ii) such limited liability company

Spectrum Brands, Inc. 5

records of each Delaware LLC Guarantor that we have considered appropriate, including the certificate of formation and operating agreement of each Delaware LLC Guarantor certified by each such Delaware LLC Guarantor, respectively, as in effect on the date of this letter and copies of the resolutions of the direct or indirect manager or sole or managing member of each Delaware LLC Guarantor, relating to the issuance of the Guarantees, certified by each such Delaware LLC Guarantor, respectively, as in effect on the date of this letter; and (iii) such other certificates, agreements and documents as we deemed relevant and necessary as a basis for the opinions expressed below. We have also relied upon oral and written statements of officers and representatives of the Company, the representations and warranties of the Company and the Guarantors made in the Documents as to factual matters and upon certificates of public officials and the officers of the Company and the Guarantors.

In our examination of the documents referred to above, we have assumed, without independent investigation, the genuineness of all signatures, the legal capacity of all individuals who have executed any of the documents reviewed by us, the authenticity of all documents submitted to us as originals, the conformity to the originals of all documents submitted to us as certified, photostatic, reproduced or conformed copies of valid existing agreements or other documents, the authenticity of all such latter documents and that the statements regarding matters of fact in the certificates, records, agreements, instruments and documents that we have examined are accurate and complete. We have also assumed, without independent investigation, that: (i) each Non-Delaware Guarantor is validly existing and in good standing under the laws of its jurisdiction of organization,

Spectrum Brands, Inc. 6

(ii) each Non-Delaware Guarantor has all necessary power and authority to execute, deliver and perform its obligations under the Indentures and the Guarantees, (iii) the execution, delivery and performance by each Non-Delaware Guarantor of the Indentures and the Guarantees has been duly authorized by all necessary corporate action or limited liability company action, as applicable, and do not violate such party’s certificate or articles of incorporation, articles of association, by-laws, operating agreements or other organizational documents or the laws of its jurisdiction of organization and (iv) the due execution and delivery of the Indentures and the Guarantees by each Non-Delaware Guarantor under the laws of its jurisdiction of organization.

Based upon the above, and subject to the stated assumptions, exceptions and qualifications, we are of the opinion that:

1. The Notes constitute legal, valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, except that the enforceability of the Notes may be subject to bankruptcy, insolvency, reorganization, fraudulent conveyance or transfer, moratorium or similar laws affecting creditors’ rights generally and subject to general principles of equity (regardless of whether enforceability is considered in a proceeding in equity or at law).

2. The Guarantees with respect to the Notes constitute legal, valid and binding obligations of each of the Guarantors, enforceable against each of the Guarantors in accordance with their terms, except that enforceability of such Guarantees may be subject to bankruptcy, insolvency, reorganization, fraudulent conveyance or transfer, moratorium or similar laws affecting creditors’ rights generally and subject to general principles of equity (regardless of whether enforcement is considered in a proceeding in equity or at law).
